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
Local GPIO output value
