GPP_​E09/USB_​OC0#/USB-C_​GPP_​E09

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 kΩ 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..

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 kΩ 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.

GPP_​B14/USB_​OC2#/USB-C_​GPP_​B14

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 kΩ pull-up resistor is required to be connected to the power-rail. The USB_​OC2# pin is multiplexed on the GPP_​B14, which is a strap for Top Swap Override. A 100 kΩ 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..
