Local GPIO Output Value This value is output on the
GPO1 Output GPIO pin when the GPIO function is enabled, the local
7 RW 0
Value GPIO direction is Output, and remote GPIO control is
disabled.
Remote GPIO Control
1: Enable GPIO control from remote Deserializer. The
GPO1 Remote
6 RW 1 GPIO pin needs to be an output, and the value is
Enable
received from the remote Deserializer.
0: Disable GPIO control from remote Deserializer.
1: Input
5 GPO1 Direction RW 0
0: Output
1: GPIO enable
4 GPO0 Enable RW 1
GPO[0] and
0: Tri-state
0x0D GPO[1]
Local GPIO Output Value This value is output on the
Configuration
GPO0 Output GPIO pin when the GPIO function is enabled, the local
3 RW 0
Value GPIO direction is Output, and remote GPIO control is
disabled.
Remote GPIO Control
1: Enable GPIO control from remote Deserializer. The
GPO0 Remote
2 RW 1 GPIO pin needs to be an output, and the value is
Enable
received from the remote Deserializer.
0: Disable GPIO control from remote Deserializer.
1: Input
1 GPO0 Direction RW 0
0: Output
1: GPIO enable
0 GPO0 Enable RW 1
0: Tri-state
Local GPIO Output Value This value is output on the
GPO3 Output GPIO pin when the GPIO function is enabled, the local
