Input Digital Volume Control
IVOL7
Default
IVOL7-0: Input Digital Volume; 0.375dB step, 242 Level
When the ALC1 operation is OFF, IVOL can be used as volume. When the IVOL is changed, the IVOL
is detected by zero crossing. Zero crossing timeout period is set by ZTM1-0 and FSTM bits.
The change of gain table between MIC and LINE is set by GSEL bit.
During the ALC1 operation, the writing value in IVOL7-0 bits is ignored
