... USB. Re-initialization of the USB bus connection can also be affected without requiring the pull out of the cable. The PDIUSBH12 will check for USB VBUS availability before the connection can be established. VBUS sensing is provided through OCURRENT_N pin. See the pin description for details. Sharing of ...

... 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. Either mode is backward compatible to the PDIUSBH11. ...

... LED pins as per port overcurrent condition pins. An overcurrent condition on any port can be uniquely identified in Mode 1. However, all downstream ports are disabled as a result of a single overcurrent condition. In addition to the two modes of operation, the PDIUSBH12 can also be configured to take either a 48 MHz crystal oscillator (for backward compatibility to PDIUSBH11 MHz crystal. ...

... When the 12 MHz input crystal frequency is selected, the reset value is 11. This will produce the lowest output frequency of 4 MHz which can then be programmed up by the user. The PDIUSBH12 design ensures no glitching during frequency change. The programmed value will not be changed by a bus reset. ...

... The bus reset 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 PDIUSBH12 hardware without the need of microcontroller intervention. 1999 Jul 22 Select Endpoint ...

... For these features, any of the Set / Clear Feature commands can be used. The specific port assignment is ignored. When the PDIUSBH12 is configured in mode 1, there is still only one power switch output but there are two 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 (nominal duration of 10 ms), this bit indicates a ‘0’. Power A ‘1’ indicates that power is supplied to downstream ports. Since the PDIUSBH12 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. This bit is only valid when Connect bit is a ‘ ...
