or as a dedicated ADC overflow pin indicating an over-range condition anywhere in the ADC signal
path for either the left or right channel. The Functionx bits determine the operation of the pin. When
configured as a GPO with the output driven low, the driver is a CMOS driver. When configured to iden-
tify an ADC Overflow condition, the driver is an open drain driver requiring a pull-up resistor.
GPO, Drive High Mode - The pin is configured as a general purpose output driven high.
Default = 0
Function:
RXP Input - If the pin is configured for an RXP input, the polarity bit is ignored. It is recommended that
in this mode this bit be set to 0.
Mute Mode - If the pin is configured as a dedicated mute output pin, the polarity bit determines the
polarity of the mapped pin according to the following
0 - Active low
1 - Active high
GPO, Drive Low / ADC Overflow Mode - If the pin is configured as a GPO, Drive Low / ADC Overflow
Mode pin, the polarity bit is ignored. It is recommended that in this mode this bit be set to 0.
GPO, Drive High - If the pin is configured as a general-purpose output driven high, the polarity bit is
ignored. It is recommended that in this mode this bit be set to 0.
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, 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 RXPx/GPOx pin
1 - Channel mute is mapped to the RXPx/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
