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 GPOx pin
1 - Channel mute is mapped to the GPOx pin:
GPO/Overflow Mode - If the pin is configured as a GPO/Overflow Mode pin, then the Function1 and
Function0 bits determine how the output will behave according to the following table. It is recommend-
ed that in this mode the remaining functional bits be set to 0.
GPO, Drive High Mode - If the pin is configured as a general purpose output, then 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.
