DAC Channel Mute (Address 07h)
AOUTX Volume Control (Addresses 08h-0D)
Function:
The Digital-to-Analog converters of the CS42436 will mute the output following the reception of 8192 con-
secutive audio samples of static 0 or -1. A single sample of non-static data will release the mute. Detection
and muting is done independently for each channel. The quiescent voltage on the output will be retained
during the mute period. The muting function is affected, similar to volume control changes, by the Soft and
Zero Cross bits (SZC[1:0]).
Mute ADC Serial Port (MUTE ADC_SP)
Default = 0
0 - Disabled
1 - Enabled
Function:
When enabled, the ADC Serial Port will be muted.
Independent Channel Mute (AOUTX_MUTE)
Default = 0
0 - Disabled
1 - Enabled
Function:
The respective Digital-to-Analog converter outputs of the CS42436 will mute when enabled. The quies-
cent voltage on the outputs will be retained. The muting function is affected by the DAC Soft and Zero
Cross bits (DAC_SZC[1:0]).
Volume Control (AOUTX_VOL[7:0])
Default = 00h
Function:
The AOUTx Volume Control registers allow independent setting of the signal levels in 0.5 dB increments
from 0 dB to -127.5 dB. Volume settings are decoded as shown in
plemented as dictated by the Soft and Zero Cross bits (DAC_SZC[1:0]). All volume settings less than -
127.5 dB are equivalent to enabling the AOUTx_MUTE bit for the given channel.
