Description
Reserved.
Local GPIO Output Value. This value is output on the GPIO pin when
the GPIO function is enabled, the local GPIO direction is set to output,
and remote GPIO control is disabled.
0: Output LOW (default).
1: Output HIGH.
Determines operating mode for the GPIO pin:
x00: Functional input mode.
x10: TRI-STATE.
001: GPIO mode, output.
011: GPIO mode, input.
101: Remote-hold mode. The GPIO pin will be an output, and the
value is received from the remote Deserializer. In remote-hold mode,
data is maintained on link loss.
111: Remote-default mode. The GPIO pin will be an output, and the
value is received from the remote Deserializer. In remote-default
mode, GPIO's Output Value bit is output on link loss.
Local GPIO Output Value. This value is output on the GPIO pin when
the GPIO function is enabled and the local GPIO direction is set to
output.
0: Output LOW (default).
1: Output HIGH.

01: GPIO mode, output.
11: GPIO mode; input.
