Register Definitions
Addr
Register Name
00H
Power Management 1
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
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.
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 MCKO bits and all bits in 00H address are
“
0
”
, all blocks are powered-down. Though the IPGA
resisters are initialized, the other registers remain unchanged. (refer to the IPGA6-0 bits description)
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
”
.
When BEEP signal is output from Speaker-Amp (Signal path: BEEP pin
SPP/SPN pins) or Mono Lineout-Amp
(Signal path: BEEP pin
AOUT pin) only, the clocks may not be present. When ADC, DAC, ALC1 or ALC2 is in
operation, the clocks must always be present.
