Local GPIO Output Value This value is output on the GPIO pin when
the GPIO function is enabled, the local GPIO direction is Output, and
remote GPIO control is disabled.
0: Output LOW (default)
1: Output HIGH
Remote GPIO Control
0: Disable GPIO control from remote Deserializer (default)
1: Enable GPIO control from remote Deserializer. The GPIO pin will
be an output, and the value is received from the remote Deserializer.
Local GPIO Direction
0: Output (default)
1: Input
GPIO Function Enable
0: Enable normal operation (default)
1: Enable GPIO operation
