CAd = X Node ID = 01h Verb ID = 716h Payload = xxh

Bits Type Default Description

31:8 Read Only 000000h Reserved

7:4 Read Only 0h

GPIO[7:4] Enable Mask: Not Supported.

3:0 Read/Write 0h

GPIO[3:0] Enable Mask: If the bit associated

with a pin is 0, the pin is disabled, and must be in

a Hi-Z state.

If the bit is a 1, the GPIO pin is enabled and the

pin’s behavior will be determined by the GPIO

Direction control.
