PMADC: ADC Block Power Control
PMDAC: DAC Block Power Control
PMAO: Mono Line Out Power Control
PMSPK: Speaker Block Power Control
PMVCM: VCOM Block Power Control
PMPFIL: Programmable Filter Block (HPF/ LPF/ 5-Band EQ/ ALC) Power Control
When any block of ADC, DAC, SPK, or Programmable digital filter is powered-up (PMADC bit = “1”or PMDAC bit
= “1” or PMSPK bit = “1” PMPFIL bit = “1”), the clocks must always be present.
Each block can be powered-down respectively by writing “0” to 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.
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 be “0”.

When the PMADC bit changes from “0” to “1”, the initialization cycle (1059/fs=133ms@8kHz) starts. After
initializing, digital data of the ADC is output.
