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.
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 Amplifier Power Control
0: Power down (default)
1: Power up
PMBP: BEEP Input Power Management
0: Power down (default)
1: Power up
When PMBP bit = “0”, the path from BEEP to speaker is still connected. Set BEEPS bit = “0” to disconnect
this path. The path from BEEP to mono lineout is the same. It can be disconnected by setting BEEPA bit = “0”.
PMVCM: VCOM Block Power Control
0: Power down (default)
1: Power up
PMPFIL: Programmable Filter Block (HPF/ LPF/ 5-Band EQ/ ALC) Power Control
0: Power down (default)
1: Power up
All blocks can be powered-down by writing “0” to the address “00H”, PMPLL, PMV, PMMP, PMDM, DMPE and
MCKO bits. In this case, register values are maintained.
PMVCM bit must be “1” when one of bocks is powered-up. PMVCM bit can only be “0” when the address “00H”
and all power management bits (PMPLL, PMV, PMMP, PMDM, DMPE and MCKO) are “0”.
When using either ADC, DAC, digital microphone or Programmable Filter (PMADL bit = “1”, PMDM bit =”1”,
PMDAC bit = “1” or PMPFIL bit = “1”), clock must be supplied.
