Default
PMADC: ADC Block Power Control
0: Power down (Default)
1: Power up
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.
PMMIC: MIC In Block (MIC-Amp and ALC1) Power Control
0: Power down (Default)
1: Power up
PMDAC: DAC Block Power Control
0: Power down (Default)
1: Power up
PMAO: Mono Line Out Power Control
0: Power down (Default)
1: Power up
PMSPK: Speaker Block Power Control
0: Power down (Default)
1: Power up
PMBP: BEEP In Power Control
0: Power down (Default)
1: Power up
PMVCM: VCOM Block Power Control
0: Power down (Default)
1: Power up
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 PMXTL bits and all bits in 00H address are “0”, all blocks are powered-down. The register values
remain unchanged.
When any of the blocks are powered-up, the PMVCM bit must be set to “1”. When PMPLL and PMXTL bits and all
bits in 00H address are “0”, PMVCM bit can write to “0”.
When BEEP signal is output from Speaker-Amp (Signal path: BEEP pin
à
SPP/SPN pins) or Mono Lineout-Amp
(Signal path: BEEP pin
à
AOUT pin) only, the clocks may not be present. When ADC, DAC, ALC1 or ALC2 is in
operation, the clocks must always be present.
