ignored. It is recommended that in this mode this bit be set to 0.
6.28.3 FUNCTIONAL CONTROL (FUNCTIONX)
Default = 00000
Function:
RXP Input - If the pin is configured for an RXP input, the functional bits are ignored. It is recommended
that in this mode all the functional bits be set to 0.
Mute Mode - If the pin is configured as a dedicated mute pin, then the functional bits determine which
channel mutes will be mapped to this pin according to the following table.
0 - Channel mute is not mapped to the RXPx/GPOx pin
1 - Channel mute is mapped to the RXPx/GPOx pin:
RXPx/GPOx
RXP7/GPO7
pin 42
RXP6/GPO6
pin 43
RXP5/GPO5
pin 44
RXP4/GPO4

GPO, Drive Low / ADC Overflow Mode - If the pin is configured as a GPO, Drive Low / ADC Overflow
