Description
Reserved.
GPIO3 Output
ValueD_GPIO
3 Output Value
Local GPIO Output Value. This value is output on the GPIO pin when the GPIO function
is enabled, the local GPIO direction is set to output, and remote GPIO control is disabled.
0: Output LOW (default).
1: Output HIGH.
If PORT1_SEL is set, this register controls the D_GPIO3 pin.
GPIO3
Determines operating mode for the GPIO pin:
ModeD_GPIO3 x00: Functional input mode.
Mode
x10: TRI-STATE™.
001: GPIO mode, output.
011: GPIO mode, input.
101: Remote-hold mode. The GPIO pin will be an output, and the value is received from
the remote Deserializer. In remote-hold mode, data is maintained on link loss.
111: Remote-default mode. The GPIO pin will be an output, and the value is received
from the remote Deserializer. In remote-default mode, GPIO's Output Value bit is output
on link loss.
If PORT1_SEL is set, this register controls the D_GPIO3 pin.
GPIO6_REG
Output Value
Local GPIO Output Value. This value is output on the GPIO pin when the GPIO function
is enabled and the local GPIO direction is set to output.
0: Output LOW (default).
1: Output HIGH.
Reserved.
GPIO6_REG
Mode
Determines operating mode for the GPIO pin:
00: Functional input mode.
10: TRI-STATE™.
01: GPIO mode, output.
11: GPIO mode; input.
GPIO5_REG
Output Value
Local GPIO Output Value. This value is output on the GPIO pin when the GPIO function
is enabled and the local GPIO direction is set to output.
0: Output LOW (default).
1: Output HIGH.
Reserved.
GPIO5_REG
Mode
Determines operating mode for the GPIO pin:
00: Functional input mode.
10: TRI-STATE™.
01: GPIO mode, output.
11: GPIO mode; input.
