GPIO3 and D_GPIO3 Configuration
If PORT1_SEL is set, this register controls the D_GPIO3 pin
0
Reserved (No GPIO 4)
0
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
Remote GPIO Control
1: Enable GPIO control from remote Serializer. The GPIO pin
will be an output, and the value is received from the remote
Serializer.
0: Disable GPIO control from remote Serializer.
0
The GPIO DIR and GPIO EN configures the pad in input
direction or output direction for functional mode or GPIO mode.
