ALCA recovery operation.
When IVOLAC bit = “1”, IVAL7-0 bits control both Lch and Rch volume level, while register values of
IVAL7-0 bits are not written to IVAR7-0 bits. When IVOLC bit = “0”, IVAL7-0 bits control Lch level and
IVAR7-0 bits control Rch level, respectively.
A period of recovery operation when any limiter operation does not occur during the ALCA operation.
When the IVOL perform zero crossing or timeout, the IVOL value is changed by the μP WRITE operation,
Default: “00” (4times)
