Function:
Mute Mode - If the pin is configured as a dedicated mute pin, the functional bits determine which chan-
nel mutes will be mapped to this pin according to the following table.
0 - Channel mute is not mapped to the GPOx pin
1 - Channel mute is mapped to the GPOx pin:
GPO, Drive Low / ADC Overflow Mode - If the pin is configured as a GPO, Drive Low / ADC Overflow
Mode pin, the Function1 and Function0 bits determine how the output will behave according to the
following table. It is recommended that in this mode the remaining functional bits be set to 0.
GPO, Drive High - If the pin is configured as a general-purpose output, the functional bits are ignored
and the pin is driven high. It is recommended that in this mode all the functional bits be set to 0.
