RX3MM

Right Auxiliary 3 Mix Mute

0 = Mix Enabled

1 = Mix Muted

RX3M4:0

Right Auxiliary 3 Mix Gain/Attenuation Select. Least significant bit represents –1.5 dB. Referred to

2.0 V p-p DAC1 output level.

00000 = +12.0 dB Gain

01000 = 0.0 dB

11111 = –34.5 dB Attenuation

res

Reserved for future expansion. To ensure future compatibility, write “0” to all reserved bits.

Initial default state after reset: 1000 1000 1000 1000 (8888 hex). Cleared to default and cannot be written to when:

the RESET pin is asserted LO; when the PWRDWN pin is asserted LO; when the PDNO bit in Control Register

Address 0 is set to “1” (all conversions disabled); or when the AAMEN bit (analog input to analog mix disabled), or

the ANAEN bit (analog channels powered down) in Control Register Address 27 is reset to “0.”
