Manual Mode
The AK4651 becomes a manual mode at ALC1 bit = “0”. The mode is used in the case shown below.
(1) After exiting reset state, set up the registers for the ALC1 operation (ZTM1-0, LMTH and etc)
(2) When the registers for the ALC1 operation (Limiter period, Recovery period and etc) are changed.
For example; When the change of the sampling frequency.
(3) When IPGA is used as a manual volume.
When writing to the IPGA5-0 bits continually, the control register should be written by an interval more than zero
crossing timeout.
