0 - Channel mute is not mapped to the MUTEC pin
1 - Channel mute is mapped to the MUTEC pin
Function:
Determines which channel mutes will be mapped to the MUTEC pin. If no channel mute bits are
mapped, then the MUTEC pin is driven to the "active" state as defined by the POLARITY bit. These
Channel Mute Select bits are "ANDed" together in order for the MUTEC pin to go active. This means
that if multiple Channel Mutes are selected to be mapped to the MUTEC pin, then all corresponding
channels must be muted before the MUTEC will go active.

RXP/General Purpose Pin Control (addresses 29h to 2Fh)
6.28.1 MODE CONTROL (MODEX)
Default = 00
00 - RXP Input
01 - Mute Mode
10 - GPO/Overflow Mode
11 - GPO, Drive High Mode
Function:
RXP Input - The pin is configured as a receiver input which can then be muxed to either the TXP pin
or to the internal receiver.
Mute Mode - The pin is configured as a dedicated mute pin. The muting function is controlled by the
Function bits.
GPO, Drive Low / ADC Overflow Mode - The pin is configured as a general purpose output driven low
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.
6.28.2 POLARITY SELECT (POLARITY)
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, then 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
