When BEEP signal is output from Speaker-Amp (Signal path: BEEP pin
(Signal path: BEEP pin
operation, the clocks must always be present.
Each block can be powered-down respectively by writing “0” in each bit. When the PDN pin is “L”, all blocks are
powered-down.
When PMPLL and MCKO bits and all bits in 00H address are “0”, all blocks are powered-down. The registers remain
unchanged.
When any of the blocks are powered-up, the PMVCM bit must be set to “1”. When PMPLL and MCKO bits and all
bits in 00H address are “0”, PMVCM bit can write to “0”.

Even if PMBP bit is “0”, the path is still connected between BEEP and AOUT/SPK-Amp. BEEPS and BEEPA
bits should be set to “0” to disconnect these paths.
When the PMADC bit changes from “0” to “1”, the initialization cycle (1059/fs=133ms@8kHz when ADRST
bit = “0”) starts. After initializing, digital data of the ADC is output.
