All

GPP_​E09/USB_​OC0#

I

Overcurrent Indicators: This signal set the corresponding bit in the xHCI controller to indicate that an overcurrent condition has occurred.

When configured as OC# pin, a 10 kohm pull-up resistor is required to be connected to the power-rail. When this pin is configured as GPIO, no pull-up resistor is required.

Notes:

  1. OC# pins are not 5 V tolerant.
  2. OC# pins can be shared between USB ports.
  3. Each USB connector should only have one OC# pin protection.

All

GPP_​B14/USB_​OC1#/DDSP_​HPDB#/DISP_​MISCB/

I

Overcurrent Indicators: This signal set the corresponding bit in the xHCI controller to indicate that an overcurrent condition has occurred.

When configured as OC# pin, a 100 kohm pullup resistor is required to be connected to the power-rail. The USB_​OC1# pin is multiplexed on the GPP_​B14, which is a strap for Top Swap Override. A 100 kohm pull-up ensures the strap functionality is not inadvertently asserted to enable the Top Swap mode Override. When this pin is configured as GPIO, no pull-up resistor is required.

Notes:

  1. OC# pins are not 5 V tolerant.
  2. OC# pins can be shared between USB ports.
  3. Each USB connector should only have one OC# pin protection.
