"Power supply setting check (RF and SRAM) of the GNSS Domain"
When turning ON the SRAM for GNSS or RF, also turn ON the PWD_GNSS.
When turning OFF the PWD_GNSS, also turn OFF the SRAM for GNSS and RF.

To turn ON the PWD_GNSS and SRAM for GNSS, RF:
PWD_CTL=0x30003000
ANA_PW_CTL=0x00020002 | (0x03F03F0 & RF power supply setting)
GNSS_RAMMODE_SEL=0x3F000FFF

To turn OFF the PWD_GNSS and SRAM for GNSS, RF:
PWD_CTL=0x20000000
GNSS_RAMMODE_SEL=0x3F000000
ANA_PW_CTL=0x03F00000
"Power supply setting check of the Sensor Domain"
When turning ON the SRAM for SCU, HPADC, or LPADC, also turn ON the PWD_SCU.
When turning OFF the PWD_SCU, also turn OFF the SRAM for SCU, HPADC, and LPADC.

To turn ON the PWD_SCU, SRAM for SCU, HPADC, and LPADC:
PWD_CTL=0x00010001
ANA_PW_CTL=0x30003000 & (HPADC and LPADC power supply setting)
TOP_SCU_RAMMODE_SEL=0x0000133F & SRAM for SCU power supply setting

To turn OFF the PWD_SCU, SRAM for SCU, HPADC, and LPADC:
PWD_CTL=0x00010001
ANA_PW_CTL=0x30000000
TOP_SCU_RAMMODE_SEL=0x00001300
"Power supply setting check of the Application Domain"
When turning ON power supply layers lower than the PWD_APP, also turn ON the PWD_APP.
When turning OFF the PWD_APP, also turn OFF the power supply layers lower than the
PWD_APP.
Note:
The layers lower than PWD_APP are as follows:
PWD_APP_AUD, PWD_APP_SUB, PWD_APP_DSP, SRAM for Application Processor

To turn ON the power supply layers lower than the PWD_APP:
PWD_CTL=0x01000100 | (0x46004600 & PWD_APP_(AUD/SUB/DSP) power supply
setting)
APPDSP_RAMMODE_SEL0=0x3F000FFF
APPDSP_RAMMODE_SEL1=0x3F000FFF

To turn OFF the PWD_APP:
PWD_CTL=0x47000000
APPDSP_RAMMODE_SEL0=0x3F000000
APPDSP_RAMMODE_SEL1=0x3F000000
