70 / 90 page  70 DS583F1 CS42516 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, 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. 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, 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 RXPx/GPOx Reg Address Function4 Function3 Function2 Function1 Function0 RXP7/GPO7 pin 42 29h M_AOUTA1 M_AOUTB1 M_AOUTA2 M_AOUTB2 M_AOUTA3 M_AOUTB3 Reserved RXP6/GPO6 pin 43 2Ah M_AOUTA1 M_AOUTB1 M_AOUTA2 M_AOUTB2 M_AOUTA3 M_AOUTB3 Reserved RXP5/GPO5 pin 44 2Bh M_AOUTA1 M_AOUTB1 M_AOUTA2 M_AOUTB2 M_AOUTA3 M_AOUTB3 Reserved RXP4/GPO4 pin 45 2Ch M_AOUTA1 M_AOUTB1 M_AOUTA2 M_AOUTB2 M_AOUTA3 M_AOUTB3 Reserved RXP3/GPO3 pin 46 2Dh M_AOUTA1 M_AOUTB1 M_AOUTA2 M_AOUTB2 M_AOUTA3 M_AOUTB3 Reserved RXP2/GPO2 pin 47 2Eh M_AOUTA1 M_AOUTB1 M_AOUTA2 M_AOUTB2 M_AOUTA3 M_AOUTB3 Reserved Reserved RXP1/GPO1 pin 48 2Fh M_AOUTA1 M_AOUTB1 M_AOUTA2 M_AOUTB2 M_AOUTA3 M_AOUTB3 Reserved Reserved |
