WWDT_GetCounter()

__STATIC_INLINE uint32_t WWDT_GetCounter

(

void

)

This function to reflects current WWDT counter value.

Returns

Return current WWDT counter value

WWDT_GetIntFlag()

__STATIC_INLINE bool WWDT_GetIntFlag

(

void

)

This function is used to indicate WWDT compare match interrupt flag.

Returns

WWDT compare match interrupt occurred or not

Return values

false	WWDT compare match interrupt did not occur
true	WWDT compare match interrupt occurred

WWDT_GetResetFlag()

__STATIC_INLINE bool WWDT_GetResetFlag

(

void

)

This function is use to get WWDT time-out reset system flag.

Returns

WWDT reset system or not

Return values

false	WWDT did not cause system reset
true	WWDT caused system reset

WWDT_GetWWDTFFlag()

__STATIC_INLINE bool WWDT_GetWWDTFFlag

(

void

)

This function is used to indicate WWDT compare match event flag.

Returns

WWDT compare match interrupt occurred or not

Return values

false	WWDT compare match interrupt did not occur
true	WWDT compare match interrupt occurred

WWDT_Open()

void WWDT_Open	(	WWDT_PrescaleDef	preScale,
		uint32_t	u32CmpValue,
		uint32_t	u32EnableInt
	)

This function make WWDT module start counting with different counter period and compared window value.

Parameters

[in]	preScale	Prescale period for the WWDT counter period. Valid values are: WWDT_PRESCALER_1 WWDT_PRESCALER_2 WWDT_PRESCALER_4 WWDT_PRESCALER_8 WWDT_PRESCALER_16 WWDT_PRESCALER_32 WWDT_PRESCALER_64 WWDT_PRESCALER_128 WWDT_PRESCALER_192 WWDT_PRESCALER_256 WWDT_PRESCALER_384 WWDT_PRESCALER_512 WWDT_PRESCALER_768 WWDT_PRESCALER_1024 WWDT_PRESCALER_1536 WWDT_PRESCALER_2048
[in]	u32CmpValue	Window compared value. Valid values are between 0x0 to 0x3F
[in]	u32EnableInt	Enable WWDT interrupt or not. Valid values are TRUE and FALSE

Returns

None

Note

Application can call this function can only once after boot up

WWDT_ReloadCounter()

__STATIC_INLINE void WWDT_ReloadCounter

(

void

)

This function is used to reload the WWDT counter value to 0x3F.

Returns

None

After WWDT enabled, application must reload WWDT counter while current counter is less than compare value and larger than 0, otherwise WWDT will cause system reset.
