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 GPIO0 Control
1: Enable GPIO control from remote Serializer. The GPIO
pin will be an output, and the value is received from the
remote Deserializer.
0: Disable GPIO control from remote Serializer
Local GPIO Direction
1: Input
0: Output
GPIO Function Enable
1: Enable GPIO operation
0: Enable normal operation
Local GPIO Output Value
This value is output on the GPIO when the GPIO function
is enabled, the local GPIO direction is Output, and remote
GPIO control is disabled.
Remote GPIO2 Control
1: Enable GPIO control from remote Serializer. The GPIO
pin will be an output, and the value is received from the
remote Deserializer.
0: Disable GPIO control from remote Serializer.
Local GPIO Direction
1: Input
