wdt_hal_init() function
Initialize one of the WDTs associated HAL context This function initializes one of the WDTs (MWDT0, MWDT1, or RWDT) hardware by doing the following: - Disables the WDT and all of its stages - Sets some registers with default values - Sets the WDTs source clock prescaler (not applicable to RWDT) - Optionally enables the level interrupt The HAL context is initialized by storing the type (i.e. MWDT or RWDT) of this WDT instance, and a pointer to the associated registers.
Syntax
void wdt_hal_init(wdt_hal_context_t *hal,
wdt_inst_t wdt_inst,
uint32_t prescaler,
bool enable_intr);
Implemented in ![]()
wdt_hal_iram.c:14
Notes
Although the WDTs on the ESP32 have an edge interrupt, this HAL does not utilize it and will always disables it. RWDT does not have a prescaler. Its tick rate is equal to the frequency of its source clock (RTC slow clock).

Description
Disable write protection of the WDT registers
Enable write protection of the WDT registers
Configure a particular stage of a WDT
Disable the WDT
Feed the WDT Feeding the WDT will reset the internal count and current stage.
Enable the WDT The WDT will start counting when enabled. This function also feeds the WDT before enabling it.
Check if the WDT is enabled
Handle WDT interrupt Clears the interrupt status bit and feeds the WDT
Deinitialize a WDT and its HAL context This function deinitializes a WDT by feeding then disabling it. The WDT's interrupt is also cleared and disabled. The HAL context is cleared.
