WDT_Close
__STATIC_INLINE void WDT_Close(void)
This function stops WDT counting and disable WDT module.
Definition: wdt.h:117
WDT_EnableInt
__STATIC_INLINE void WDT_EnableInt(void)
This function enables the WDT time-out interrupt.
Definition: wdt.h:128
WDT_Open
void WDT_Open(uint32_t u32TimeoutInterval, uint32_t u32ResetDelay, uint32_t u32EnableReset, uint32_t u32EnableWakeup)
This function make WDT module start counting with different time-out interval.
Definition: wdt.c:47
WDT_DisableInt
__STATIC_INLINE void WDT_DisableInt(void)
This function disables the WDT time-out interrupt.
