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.

GPIO[3:0] Direction: If a bit is a 0, the associ-
ated GPIO signal is configured as an input.
If the bit is set to a 1, the associated GPIO signal
is configured as an output.
