DESCRIPTION
The Philips Semiconductors PDIUSBH11 is a compound USB hub
IC (hub plus embedded function).
It is used in a microcontroller based system and communicates with
the system microcontroller over the I
2
C serial bus. This modular
approach to implementing a hub and embedded function allows the
designer to maintain the system microcontroller of choice and retain
existing architecture. This cuts down development time and offers
the most cost-effective solution.
Ideal applications for the IC include computer monitors and
keyboards.
The PDIUSBH11 conforms to the USB specification 1.0 and I
2
C
serial interface specification. It is also compliant with the USB
Human Input Device and Monitor Control Class specifications.
The embedded function of the PDIUSBH11 appears as PORT1 to
the host system and the four downstream ports are numbered 2
through 5.

Analog Transceivers
These transceivers interface directly to the USB cables through
some termination resistors. They are capable of transmitting and
receiving serial data at both "full speed" (12 Mbit/s) and "low speed"
(1.5 Mbit/s) data rates.
Hub Repeater
The hub repeater is responsible for managing connectivity on a per
packet basis. It implements packet signaling connectivity and
resume connectivity.
Low speed devices can be connected to downstream ports since the
repeater will not propagate upstream packets to downstream ports,
to which low speed devices are connected, unless they are
preceded by a PREAMBLE PID.
End of Frame Timers
This block contains the specified EOF1 and EOF2 timers which are
used to detect loss-of-activity and babble error conditions in the hub
repeater. The timers also maintain the low-speed keep-alive strobe
which is sent at the beginning of a frame.
General and Individual Port Controller
The general and individual port controllers together provide status
and control of individual downstream ports. Via the I
2
C-interface a
microcontroller can access the downstream ports and request or
change the status of each individual port.
Any change in the status or settings of the individual port will result
in an interrupt request. Via an interrupt register, the servicing
microcontroller can look up the downstream port which generated
the interrupt and request its new status. Any port status change can
then be reported to the host via the hub status change (interrupt)
endpoint.
Bit Clock Recovery
The bit clock recovery circuit recovers the clock from the incoming
USB data stream using (4X) over-sampling principle. It is able to
track jitter and frequency drift specified by the USB spec.
Philips Serial Interface Engine (PSIE)
The Philips SIE implements the full USB protocol layer. It is
completely hardwired for speed and needs no firmware intervention.
The functions of this block include: synchronization pattern
recognition, parallel / serial conversion, bit stuffing / destuffing, CRC
checking / generation, PID verification / generation, address
recognition, handshake evaluation / generation.
Memory Management Unit (MMU) and Integrated RAM
The MMU and the integrated RAM is used to handle the large
difference in data-rate between USB, running in burst of 12 Mbit/s
and the I
2
C interface to the microcontroller, running at 100 kbit/s.
This allows the microcontroller to read and write USB packets at its
own (low) speed through I
2
C.
I
2
C Slave Interface
This block implements the necessary I
2
C interface protocol. A slave
I
2
C allows for simple micro-coding. An interrupt is used to alert the
microcontroller whenever the PDIUSBH11 needs attention. As a
slave I
2
C device, the PDIUSBH11 I
2
C clock: SCL is an input and is
controlled by the microcontroller.

PIN DESCRIPTION
The PDIUSBH11 has two modes of operation. The first mode
(Mode 0) enables the pins DNx_EN_N to power a LED indicating
the port is enabled. The second mode (Mode 1) utilizes the LED
enable pins as per port overcurrent condition pins.
The voltage level at power up on the TEST1 and TEST2 pins
determine the PDIUSBH11 mode of operation. When both of the
pins are connected to Ground, Mode 0 is enabled. When pins
TEST1 and TEST2 are connected to Vcc, Mode 1 is enabled. Note
that in Mode 1 the pin DN2_EN_N remains an LED enable pin. Pin
TEST3 should always be connected to Ground at all times.

I
2
C Interface
.
The I
2
C bus is used to interface to an external microcontroller
needed to control the operation of the hub. For cost consideration,
the target system microcontroller can be shared and utilized for this
purpose. The PDIUSBH11 implements a slave I
2
C interface. When
the PDIUSBH11 needs to communicate with the microcontroller it
asserts an interrupt signal. The microcontroller services this
interrupt by reading the appropriate status register on the
PDIUSBH11 through the I
2
C bus. (For more information about the
I
2
C serial bus, refer to the I
2
C handbook, Philips order number 9397
750 00013).
The I
2
C interface on the PDIUSBH11 defines two types of
transactions :
1. command transaction
A command transaction is used to define which data (e.g., status
byte, buffer data, ...) will be read from / written to the USB
interface in the next data transaction. A data transaction usually
follows a command transaction.
2. data transaction
A data transaction reads data from / writes data to the USB
interface. The meaning of the data is dependent on the
command transaction which was sent before the data
transaction.
Two addresses are used to differentiate between command and
data transactions. Writing to the command address is interpreted as
a command, while reading from / writing to the data address is used
to transfer data between the PDIUSBH11 and the controller.

PHYSICAL ADDRESS
(MSB to LSB)
Command
0011 011 (binary)

Protocol
An I
2
C transaction starts with a `Start Condition', followed by an
address. When the address matches either the command or data
address the transaction starts and runs until a `Stop Condition' or
another `Start Condition' (repeated start) occurs.
The command address is write-only and is unable to do a read. The
next bytes in the message are interpreted as commands. Several
command bytes can be sent after one command address. Each of
the command bytes is acknowledged and passed on to the Memory
Management Unit inside the PDIUSBH11.
When the start condition address matches the data address, the
next bytes are interpreted as data. When the RW bit in the address
indicates a `master writes data to slave' (=`0') the bytes are received,
acknowledged and passed on to the Memory Management Unit. If
the RW bit in the address indicates a `master reads data from slave'
(=`1') the PDIUSBH11 will send data to the master. The I
2
C-master
must acknowledge all data bytes except the last one. In this way the
I
2
C interface knows when the last byte has been transmitted and it
then releases the SDA line so that the master controller can
generate the STOP condition.
Repeated start support allows another packet to be sent without
generating a Stop Condition.
Timing
When the master writes data to the PDIUSBH11, the data is
sampled 1 micro-second after the rising edge of SCL. When the
PDIUSBH11 writes data to the master, the data is driven 1
micro-second after the falling edge of SCL.

COMMAND DESCRIPTIONS
Command Procedure
There are four basic types of commands: Initialization, Data, Hub Specific and General commands. Respectively, these are used to initialize the
hub and embedded function; for data flow between the hub, embedded function and the host; some hub specific commands for controlling
individual downstream ports; and some general commands.
Initialization Commands
Initialization commands are used during the enumeration process of the USB network. These commands are used to enable the hub and
embedded function endpoints. They are also used to set the USB assigned address.
Set Address / Enable
Command
: D0h (Hub), D1h (Embedded Function)
Data
: Write 1 byte
This command is used to set the USB assigned address and enable the hub or embedded function respectively. The hub always powers up
disabled and should be enabled after a bus RESET.

Data Flow Commands
Data flow commands are used to manage the data transmission between the USB endpoints and the monitor. Much of the data flow is initiated
via an interrupt to the microcontroller. The microcontroller utilizes these commands to access and determine whether the endpoint FIFOs have
valid data.
Read Interrupt Register
Command
: F4h
Data
: Read 1 byte
This command indicates the origin of an interrupt. A "1" indicates an interrupt occurred at this endpoint. The bits are cleared by reading the
endpoint status register through Read Endpoint Status command.
After a bus reset an interrupt will be generated, however all bits in the interrupt register will be 0. The interrupt is internally cleared by reading
the interrupt register. A bus reset is completely identical to the hardware reset through the RESET_N pin with the sole difference of interrupt
notification.
The hub interrupt endpoint is handled internally by the PDIUSBH11 hardware without the need of microcontroller intervention.

Read Last Transaction Status
Command
: 4044h
Data
: Read 1 byte
The
Read Last Transaction Status command is followed by one data read that returns the status of the last transaction of the endpoint. This
command also resets the corresponding interrupt flag in the interrupt register, and clears the status, indicating that it was read.
This command is useful for debugging purposes. Since it keeps track of every transaction, the status information is overwritten for each new
transaction.

Read Buffer
Command
: F0h
Data
: Read multiple bytes (max 10)
The Read Buffer command is followed by a number of data reads, which return the contents of the selected endpoint data buffer. After each
read, the internal buffer pointer is incremented by 1.
The buffer pointer is not reset to the buffer start by the Read Buffer command. This means that reading or writing a buffer can be interrupted by
any other command (except for Select Endpoint), or can be done by more than one I2C transaction (read the first 2 bytes to get the number of
data bytes, then read the rest in other transactions).
The data in the buffer are organized as follows:
·
byte 0:
reserved: can have any value
·
byte 1:
Number / length of data bytes
·
byte 2:
Data byte 1

Write Buffer
Command
: F0h
Data
: Write multiple bytes (max 10)
The Write Buffer command is followed by a number of data writes, which load the endpoints buffer. The data must be organized in the same
way as described in the Read Buffer command. The first byte (reserved) should always be 0. As in the Read Buffer command, the data can be
split up into different I2C data transactions.
WARNING
There is no protection against writing or reading over a buffer's boundary or against writing into an OUT buffer or reading from an IN buffer. Any
of these actions could cause an incorrect operation. Data in an OUT buffer are only meaningful after a successful transaction.

Clear Buffer
Command
: F2h
Data
: None
When a packet is received completely, an internal endpoint buffer full flag is set. All subsequent packets will be refused by returning a NACK.
When the microcontroller has read the data, it should free the buffer by the Clear Buffer command. When the buffer is cleared new packets will
be accepted.
Validate Buffer
Command
: FAh
Data
: None
When the microprocessor has written data into an IN buffer, it should set the buffer full flag by the Validate Buffer command. This indicates that
the data in the buffer are valid and can be sent to the host when the next IN token is received.
Set Endpoint Status
Command
: 4044h
Data
: Write 1 byte
A stalled control endpoint is automatically unstalled when it receives a SETUP token, regardless of the content of the packet. If the endpoint
should stay in its stalled state, the microcontroller can restall it.
When a stalled endpoint is unstalled (either by the Set Endpoint Status command or by receiving a SETUP token), it is also reinitialized. This
flushes the buffer and if it is an OUT buffer it waits for a DATA 0 PID, if it is an IN buffer it writes a DATA 0 PID.
Even when unstalled, writing Set Endpoint Status to `0' initializes the endpoint.

Acknowledge Setup
Command
: F1h
Data
: None
The arrival of a SETUP packet flushes the IN buffer and disables the Validate Buffer
and Clear Buffer commands for both IN and OUT
endpoints.
The microcontroller needs to reenable these commands by the
Acknowledge Setup command. This ensures that the last SETUP packet stays
in the buffer and no packet can be sent back to the host until the microcontroller has acknowledged explicitly that it has seen the SETUP packet.
The microcontroller must send the Acknowledge Setup
command to both the IN and OUT endpoints.

Hub Commands
Hub commands are used to report connectivity and power status between the hub and the host. These commands allow the host to enable
each port individually and get any change of status such as new connectivity information.
Clear/Set Port Feature
Command
: E0E3h (Clear) and E8hEBh (Set)
Data
: Write 1 byte
When the controller receives a
Set Feature or a Clear Feature request, there are two possibilities:
·
The request applies to port 1, the embedded port. In this case the request should be handled internally by the controller.
·
If the request applies to ports 2 through 5, the controller should translate the request into a Set Feature or Clear Feature command towards
the PDIUSBH11.
When the PDIUSBH11 is configured in mode 0, there is only one power switch output and one overcurrent input. This means that the
F_PORT_POWER and C_PORT_OVERCURRENT features are not port specific. For these features, any of the Set / Clear Feature commands
can be used. The specific port assignment is ignored.
When the PDIUSBH11 is configured in mode 1, there is still only one power switch output but there are four individual overcurrent input pins
corresponding to each port. This means that the F_PORT_POWER feature is port specific and the C_PORT_OVERCURRENT feature is not
port specific.
Setting the F_PORT_POWER feature turns the power on when it is off and turns the overcurrent detection on only when the power is already
on. This allows to have a short period of overcurrent condition at the moment that power is switched on. For this reason, the F_PORT_POWER
feature needs to be set twice. Clearing this feature turns both the power and the overcurrent detection off.
The data written in the data phase is the feature code described in Table 2.

Set Status Change Bits
Command
: F7h
Data
: Write 1 byte
For assembling the hub's status change register, the device needs some additional information from the controller, i.e. the Local Power Status
Change bit and the embedded function Status Change bit.
These are provided by the Set Status Change Bits command. This command is always followed by one data write which contains the Local
Power Status Change bit at the LSB and the embedded function Status Change bit at position 1. All other bits should be 0.

EMBEDDED FUNCTION
The USB host sees no difference between the embedded function and a function connected to one of the downstream ports. Some of the port
commands sent by the host must be handled appropriately by the embedded function to appear as any other downstream port.
The micro controller maintains a series of status and status change bits for the embedded function as described in the Get Port Status
command section. From these bits, the Status Change bit for the embedded function is derived (i.e. the port specific Status Change bits). This
Status Change bit is then provided to the PDIUSBH11 by the Set Status Change Bits command.

Host Requests
SetFeature PORT_RESET
Reinitialize the embedded function and set the Reset Change bit to indicate that the reset has completed. Reset the Enable Status bit, enable
the embedded function and set its address to 0 by the Set embedded function Address / Enable command. Disable the embedded function
interrupt endpoint by the Set Endpoint Enable command.
SetFeature PORT_ENABLE
Enable the function by the Set embedded function Address / Enable command. Set the Enable Status bit.
SetFeature PORT_SUSPEND
Disable the function by the
Set embedded function Address / Enable command. Reset the Enable Status bit and set the Suspend Status bit.
ClearFeature PORT_ENABLE
Disable the function by the
Set embedded function Address / Enable command. Reset the Enable Status bit.
ClearFeature PORT_SUSPEND
Enable the function by the
Set embedded function Address / Enable command. Set the Enable Status bit, reset the Suspend Status bit; set the
Resume Status Change bit to indicate that the resume has completed.
ClearFeature any Change Indicator
Clear the corresponding status change bit.
Babbling Condition
When the embedded function causes a babbling condition, the function is automatically disabled by the PDIUSBH11. As soon as the micro
controller detects the babbling error, it must set the Enable Status Change bit and reset the Enable Status bit.
Remote WakeUp
There are three scenarios a remote wakeup can occur. The following describes the course of actions for each of the cases:
1. The device is not suspended and the embedded port is suspended
Enable back the function by setting the enable bit in the Set Address/Enable register and update the following status bits in the
microcontroller program: reset the Suspend Status bit, set the Enable Status bit and set the Suspend Status Change bit.
2. The device is suspended and the embedded port is suspended.
Send an upstream Resume using the Send Resume command, enable back the function by setting the enable bit in the Set
Address/Enable register and update the following status bits in the microcontroller program: reset the Suspend Status bit, set the Enable
Status bit and set the Suspend Status Change bit.
3. The device is suspended and the embedded port is enabled
Send an upstream resume using the Send Resume command
