... Ideal applications for the IC include computer monitors and keyboards. The PDIUSBH11 conforms to the USB specification 1.0 and I serial interface specification 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 ...

... 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 ENDPOINT DESCRIPTIONS The following table summarizes the endpoints supported by the PDIUSBH11. ENDPOINT FUNCTION NUMBER 0 ...

... 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. ...

... 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 ...

... 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. 1997 Aug POWER ON VALUE RESERVED SETUP PACKET STALL DATA 0/1 PACKET BUFFER FULL RESERVED 11 Product specification PDIUSBH11 SV00508 ...

... The microcontroller needs to re–enable 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. 1997 Aug 01 SV00509 12 Product specification PDIUSBH11 ...

... 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 ...

... WHEN RESET IS COMPLETED (NORMAL DURATION OF 10MS), THIS BIT INDICATES A ‘0’. POWER A ‘1’ INDICATES THAT POWER IS SUPPLIED TO DOWNSTREAM PORTS. SINCE THE PDIUSBH11 SUPPORTS GANG MODE POWER SWITCHING, THIS BIT IS THE SAME FOR ALL PORTS. LOW SPEED A ‘1’ INDICATES THAT LOW SPEED DEVICE IS CONNECTED TO THIS 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. 1997 Aug 01 ...

... 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. ...
