Register Name
Operation Mode
0: ALC Disable (RESET)
1: ALC Enable
0: FADEOUT Disable (RESET)
1: FADEOUT Enable
0: FADEIN Disable (RESET)
1: FADEIN Enable
0: ALC (including FADEIN and FADEOUT) operation or initializing operation (RESET)
1: Manual Mode
0: The ALC operation corresponds to impulse noise. (RESET)
1: The ALC operation is the same as AK4516A
0: Enable (RESET)
1: Disable
In case of ZELMN = “0”, IPGA of each L/R channel do zero crossing or timeout independently, the IPGA
value is changed by the ALC operation. Zero crossing timeout is the same as the ALC recovery operation. In
case of ZELMN = “1”, the IPGA value is changed immediately.
STAT bit is “0” during initializing operation after exiting power-down by PDN pin. After the finish of the
initializing operation, STAT bit becomes “1”.
During the ALC operation, STAT bit becomes “1” after the max “1” ATT/GAIN operation is completed by
internal state.
