Page 5: Endpoint Descriptions
Philips Semiconductors USB 2-port hub ENDPOINT DESCRIPTIONS There are two endpoint configuration modes supported by the PDIUSBH12, the Single Embedded Function mode and the Multiple (3) Embedded Function mode. The Single Embedded Function mode is the default at power up reset. The Multiple (3) Embedded Function mode can be configured by writing a zero to bit 7 of the first byte of the Set Mode command. - Page 6 Philips Semiconductors USB 2-port hub PINNING The PDIUSBH12 has two modes of operation. The first mode (Mode 0) configures the pins DNx_GL_N for GoodLink second mode (Mode 1) configures the LED pins as per port overcurrent condition pins. An overcurrent condition on any port can be uniquely identified in Mode 1.

Page 11: Command Descriptions
Philips Semiconductors USB 2-port hub 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;... - Page 12 Philips Semiconductors USB 2-port hub Configuration Byte POWER ON VALUE REMOTE WAKEUP NO LAZYCLOCK CLOCK RUNNING DEBUG MODE SoftConnect CONNECT DOWNSTREAM RESISTORS NON-BLINKING LEDs EMBEDDED FUNCTION MODE Remote Wakeup A ‘1’ indicates that a remote wakeup feature is ON. Bus reset will set this bit to ‘1’.
- Page 13 Philips Semiconductors USB 2-port hub 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.

- Page 15 Set Feature or Clear Feature command towards the PDIUSBH12. When the PDIUSBH12 is configured in mode 0, there is only one power switch output and one overcurrent input. This means that the SV00834 F_PORT_POWER and C_PORT_OVERCURRENT features are not port specific.
- Page 16 Philips Semiconductors USB 2-port hub Get Port Status Command : E0h–E1h Data : Read 1 or 2 bytes The Get Port Status Command can be followed by one or two data reads. The first byte returned contains the port status. The second byte returned is the port status change byte.
- Page 17 Philips Semiconductors USB 2-port hub General Commands Send Resume Command : F6h Data : None Sends an upstream resume signal for 10 ms. This command is normally issued when the device is in suspend. The RESUME command is not followed by a data read or write.
