(

void

)

This function indicate WDT time-out evnet occurred or not.

Returns

WDT time-out evnet occurred or not

Return values

true	WDT time-out evnet occurred

WDT_GetTimeoutIntFlag()

__STATIC_INLINE bool WDT_GetTimeoutIntFlag

(

void

)

This function indicate WDT time-out interrupt occurred or not.

Returns

WDT time-out interrupt occurred or not

Return values

false	WDT time-out interrupt did not occur
true	WDT time-out interrupt occurred

WDT_GetTimeoutWakeupFlag()

__STATIC_INLINE bool WDT_GetTimeoutWakeupFlag

(

void

)

This function indicate WDT time-out waked system up or not.

Returns

WDT time-out waked system up or not

Return values

false	WDT did not wake up system
true	WDT waked up system

WDT_Open()

void WDT_Open	(	WDT_TimeoutDef	u32TimeoutInterval,
		WDT_ResetDelayDef	u32ResetDelay,
		uint32_t	u32EnableReset,
		uint32_t	u32EnableWakeup
	)

This function make WDT module start counting with different time-out interval.

Parameters

[in]	u32TimeoutInterval	Time-out interval period of WDT module. Valid values are: WDT_TIMEOUT_2POW4 WDT_TIMEOUT_2POW6 WDT_TIMEOUT_2POW8 WDT_TIMEOUT_2POW10 WDT_TIMEOUT_2POW12 WDT_TIMEOUT_2POW14 WDT_TIMEOUT_2POW16 WDT_TIMEOUT_2POW18
[in]	u32ResetDelay	Reset delay period while WDT time-out happened. Valid values are: WDT_RESET_DELAY_2CLK WDT_RESET_DELAY_17CLK WDT_RESET_DELAY_129CLK WDT_RESET_DELAY_1025CLK
[in]	u32EnableReset	Enable WDT reset system function. Valid values are TRUE and FALSE
[in]	u32EnableWakeup	Enable WDT wake-up system function. Valid values are TRUE and FALSE

Returns

None

CLK_SetWdtClkSrc(WDT_CLK_SRC_SEL_APBDIV);
WDT_Open(WDT_TIMEOUT_2POW16, WDT_RESET_DELAY_1025CLK, FALSE, FALSE);

WDT_ResetCounter()

__STATIC_INLINE void WDT_ResetCounter

(

void

)

This function is used to reset 18-bit WDT counter.

Returns

None

If WDT is activated and enabled to reset system, software must reset WDT counter before WDT time-out plus reset delay reached. Or WDT generate a reset signal.
