hal_wdt_feed()

void hal_wdt_feed

(

void

)

Feeds the WDT so that it does not bite.

Note

The WDT feeding should preferably be done in the main thread level, not in an interrupt routine.

hal_wdt_init()

void hal_wdt_init	(	uint32_t	period_ms,
		void(*)(void)	wdt_timeout_handler
	)

Initialize the WDT peripheral

Parameters

period_ms	The period in ms after which the WDT bites if not fed
wdt_timeout_handler	The handler to call in case WDT bites.

Note

The SoC will reset about 60 us after the handler is called. This handler can be used to do general house keeping before the reset.
