SMUL: Digital Soft Mute Control for SPL (Speaker Output, L-Channel)
SMUR: Digital Soft Mute Control for SPR (Speaker Output R-Channel)
Default value: 1
SPOLP/SPOLN and SPORP/SPORN can be independently muted to the zero level when SMUL and SMUR = 1.
These settings have precedence over analog volume level settings.
SMUL, SMUR = 0
SMUL, SMUR = 1
Mute disabled
Mute enabled (default)
SLV[5:0]: Gain Setting for SPL (Speaker Output L-Channel)
SRV[5:0]: Gain Setting for SPR (Speaker Output R-Channel)
Default value: 00 0000.
SPOLP/SPOLN and SPORP/SPORN can be independently controlled between 6 dB and –70 dB, with step size
depending on the gain level as shown in
Table 8
. Outputs may have zipper noise while changing levels. This
noise can be reduced by selecting zero-cross detection (register 86, ZCRS).
