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.
Remote GPIO control
1: Enable GPIO control from remote Deserializer.
The GPIO pin will be an output, and the value is
received from the remote Deserializer.
0: Disable GPIO control from remote Deserializer.
Local GPIO Direction
1: Input
0: Output
GPIO function enable
1: Enable GPIO operation
0: Enable normal operation
