When ADC bit changes from “0” to “1”, initializing cycle (8224/fs=171.3ms@fs=48kHz) starts.
After initializing cycle, digital data of ADC is output.

Analog volume (OPGA) are enabled when SPKP bit = “1” or HPP bit = “1”.
These bits can be partially powered-down by ON/OFF (“1” / “0”). When PD pin goes
“L”, all the circuit in AK4560A can be powered-down regardless of these bits in the
address.
When bit in this address goes all “0”, all the circuits in AK4560A can be also powered-
down. But contents of registers are kept.
When each block is operated, VCOM bit must go “1”. VCOM bit can write “0” when all
bits in this address can be “0”.
Except the case of IPGA=ADC=DAC=SPKP=HPP= “0” or PD pin = “L”, MCLK,
BCLK and LRCK should not be stopped.
