29 0x1D GPIO0 Config 7:4 R 0xA0 Rev-ID Revision ID: 1010: Production Device
3 RW GPIO0 Local GPIO Output Value
Output This value is output on the GPIO pin when the GPIO
Value function is enabled, the local GPIO direction is Output, and
remote GPIO control is disabled.
2 RW GPIO0 Remote GPIO0 Control
Remote 1: Enable GPIO control from remote Serializer. The GPIO
Enable pin will be an output, and the value is received from the
remote Deserializer.
0: Disable GPIO control from remote Serializer
1 RW GPIO0 Local GPIO Direction
Direction 1: Input
0: Output
0 RW GPIO0 GPIO Function Enable
Enable 1: Enable GPIO operation
0: Enable normal operation
30 0x1E GPIO2 and 7 RW 0x00 GPIO2 Local GPIO Output Value
GPIO1 Config Output This value is output on the GPIO when the GPIO function
Value is enabled, the local GPIO direction is Output, and remote
GPIO control is disabled.
6 RW GPIO2 Remote GPIO2 Control
Remote 1: Enable GPIO control from remote Serializer. The GPIO
Enable pin will be an output, and the value is received from the
remote Deserializer.
0: Disable GPIO control from remote Serializer.
5 RW GPIO2 Local GPIO Direction
Direction 1: Input
0: Output
4 RW GPIO2 GPIO Function Enable
Enable 1: Enable GPIO operation
0: Enable normal operation
3 RW GPIO1 Local GPIO Output Value
Output This value is output on the GPIO when the GPIO function
Value is enabled, the local GPIO direction is Output, and remote
GPIO control is disabled.
2 RW GPIO1 Remote GPIO1 Control
Remote 1: Enable GPIO control from remote Serializer. The GPIO
Enable pin will be an output, and the value is received from the
remote Deserializer.
