Description

Sets the power options of crystal and PLL clocks, and initiates reset by software

Fields

SW_STALL_APPCPU_C0

{reg_sw_stall_appcpu_c1[5:0] , reg_sw_stall_appcpu_c0[1:0]} == 0x86 will stall APP CPU

SW_STALL_PROCPU_C0

When RTC_CNTL_REG_SW_STALL_PROCPU_C1 is configured to 0x21, setting this bit to 0x2 stalls the CPU by SW.

SW_APPCPU_RST

APP CPU SW reset. (Note, we don’t have APP CPU for ESP32-S2)

SW_PROCPU_RST

Set this bit to reset the CPU by SW.

BB_I2C_FORCE_PD

Set this bit to FPD BB_I2C.

BB_I2C_FORCE_PU

Set this bit to FPU BB_I2C.

BBPLL_I2C_FORCE_PD

Set this bit to FPD BB_PLL _I2C.

BBPLL_I2C_FORCE_PU

Set this bit to FPU BB_PLL _I2C.

BBPLL_FORCE_PD

Set this bit to FPD BB_PLL.

BBPLL_FORCE_PU

Set this bit to FPU BB_PLL.

XTL_FORCE_PD

Set this bit to FPD the crystal oscillator.

XTL_FORCE_PU

Set this bit to FPU the crystal oscillator.

XTL_FORCE_ISO
PLL_FORCE_ISO
ANALOG_FORCE_ISO
XTL_FORCE_NOISO
PLL_FORCE_NOISO
ANALOG_FORCE_NOISO
DG_WRAP_FORCE_RST

Set this bit to force reset the digital system in deep-sleep.

DG_WRAP_FORCE_NORST

Set this bit to disable force reset to digital system in deep-sleep.

SW_SYS_RST

Set this bit to reset the system via SW.
