5. Calculate watchdog period value using WDT_GetPeriod().

Function Documentation

WDT_Disable()

void WDT_Disable ( Wdt * pWDT )

extern

Disable watchdog.

Note

The Watchdog Mode Register (WDT_MR) can be written only once. Only a processor reset resets it.

WDT_Enable()

void WDT_Enable ( Wdt * pWDT, uint32_t dwMode )

extern

Enable watchdog with given mode.

Note

The Watchdog Mode Register (WDT_MR) can be written only once. Only a processor reset resets it.

Parameters

dwMode

WDT mode to be set

WDT_GetPeriod()

uint32_t WDT_GetPeriod ( uint32_t dwMs )

extern

Watchdog get period.

Parameters

dwMs	desired watchdog period in millisecond.
