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

Description
Reserved
GPIO[7:4] Direction: Not Supported.
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.
