Initialize TIMER.

Notice that counter top must be configured separately with for instance TIMER_TopSet(). In addition, compare/capture and dead-time insertion init must be initialized separately if used. That should probably be done prior to the use of this function if configuring the TIMER to start when initialization is completed.

[in]	flags	TIMER interrupt source(s) to set to pending. Use one or more valid interrupt flags for the TIMER module (TIMER_IF_nnn) OR'ed together.

__STATIC_INLINE void TIMER_Lock ( TIMER_TypeDef * timer )

Lock some of the TIMER registers in order to protect them from being modified.

Please refer to the reference manual for TIMER registers that will be locked.

Note: If locking the TIMER registers, they must be unlocked prior to using any TIMER API functions modifying TIMER registers protected by the lock.

Parameters

[in] timer Pointer to TIMER peripheral register block.

__STATIC_INLINE uint32_t TIMER_MaxCount ( const TIMER_TypeDef * ref )

Get the Max count of the timer.

Parameters

[in] timer Pointer to TIMER peripheral register block.

Returns: The max count value of the timer. This is 0xFFFF for 16 bit timers and 0xFFFFFFFF for 32 bit timers.

void TIMER_Reset ( TIMER_TypeDef * timer )

Reset TIMER to same state as after a HW reset.

Note: The ROUTE register is NOT reset by this function, in order to allow for centralized setup of this feature.

Parameters

[in] timer Pointer to TIMER peripheral register block.

__STATIC_INLINE void TIMER_TopBufSet	(	TIMER_TypeDef *	timer,
		uint32_t	val
	)

Set top value buffer for timer.

When the top value buffer register is updated, the value is loaded into the top value register at the next wrap around. This feature is useful in order to update the top value safely when the timer is running.

Parameters

[in]	timer	Pointer to TIMER peripheral register block.
[in]	val	Value to set in top value buffer register.

__STATIC_INLINE uint32_t TIMER_TopGet ( TIMER_TypeDef * timer )

Get top value setting for timer.

Parameters

[in] timer Pointer to TIMER peripheral register block.

Returns: Current top value.

__STATIC_INLINE void TIMER_TopSet	(	TIMER_TypeDef *	timer,
		uint32_t	val
	)

Set top value for timer.

Parameters

[in]	timer	Pointer to TIMER peripheral register block.
[in]	val	Value to set in top value register.

__STATIC_INLINE void TIMER_Unlock ( TIMER_TypeDef * timer )

Unlock the TIMER so that writing to locked registers again is possible.

Parameters

[in] timer Pointer to TIMER peripheral register block.

References TIMER_TypeDef::DTLOCK, TIMER0, and TIMER_DTLOCK_LOCKKEY_UNLOCK.

__STATIC_INLINE bool TIMER_Valid ( const TIMER_TypeDef * ref )

Validate the TIMER register block pointer.

Parameters

[in] ref Pointer to TIMER peripheral register block.

Returns: true if ref points to a valid timer, false otherwise.
