PM0: MIC Block (Pre-Amp, EQ-Amp, HPF-Amp and MPWR) Power Control.
0: OFF. Output pins are Hi-z.
1: ON. In case of EQ bit = “0”, EQ-Amp is powered-down. (RESET)
PM1: IPGA (ALC) Power Control
0: OFF
1: ON (RESET)
PM2: ADC Power Control
0: OFF. SDTO pin becomes “L”.
1: ON (RESET)
When ADC bit changes from “0” to “1”, initializing cycle (8224/fs=171.3ms@fs=48kHz) starts.
Digital data of ADC is generated after initializing cycle.

1: ON (RESET)
PM5: Headphone Amplifier Power Control
0: OFF. HPL/HPR pins become Hi-z and HVCM pin becomes “L” (AGND).
1: ON (RESET)

0: OFF. MOUT pin becomes Hi-z.
1: ON (RESET)
PM7: LINEOUT Power Control

Analog volume (OPGA) are enabled when PM6 bit = “1” or PM5 bit = “1”.
These bits can be partially powered-down by ON/OFF (“1” / “0”). When PD pin goes
“L”, all the circuit in AK4561 can be powered-down regardless of these bits in the address.
When bit in this address goes all “0”, all the circuits in AK4561 can be also powered-
down. But contents of registers are kept.
When each block is operated, PM4 bit must go “1”. PM4 bit can write “0” when all bits in
this address can be “0”.
Except the case of PM6=PM5=PM3=PM2=PM1= “0” or PD pin = “L”, MCLK, BCLK
and LRCK should not be stopped.
