Detailed Description

Timer/Counter (TIMER) Peripheral API.

The timer module consists of three main parts:

General timer configuration and enable control.
Compare/capture control.
Dead time insertion control (may not be available for all timers).

Initialize TIMER.

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

Parameters

[in]	`timer`	A pointer to the TIMER peripheral register block.

		const TIMER_InitDTI_TypeDef *	`init`
	)

Initialize the TIMER DTI unit.

Parameters

__STATIC_INLINE void TIMER_IntClear	(	TIMER_TypeDef *	`timer,`
		uint32_t	`flags`
	)

Clear one or more pending TIMER interrupts.

Parameters

[in]	`timer`	Pointer to TIMER peripheral register block.
[in]	`flags`	Pending TIMER interrupt source(s) to clear. Use one or more valid interrupt flags for the TIMER module (TIMER_IF_nnn) OR'ed together.

__STATIC_INLINE void TIMER_IntDisable	(	TIMER_TypeDef *	`timer,`
		uint32_t	`flags`
	)

Disable one or more TIMER interrupts.

Parameters

[in]	`timer`	Pointer to TIMER peripheral register block.
[in]	`flags`	TIMER interrupt source(s) to disable. Use one or more valid interrupt flags for the TIMER module (TIMER_IF_nnn) OR'ed together.

__STATIC_INLINE void TIMER_IntEnable	(	TIMER_TypeDef *	`timer,`
		uint32_t	`flags`
	)

Enable one or more TIMER interrupts.

Note: Depending on the use, a pending interrupt may already be set prior to enabling the interrupt. To ignore a pending interrupt, consider using TIMER_IntClear() prior to enabling the interrupt.

Parameters

[in]	`timer`	Pointer to TIMER peripheral register block.
[in]	`flags`	TIMER interrupt source(s) to enable. Use one or more valid interrupt flags for the TIMER module (TIMER_IF_nnn) OR'ed together.

Definition at line 927 of file em_timer.h .

__STATIC_INLINE uint32_t TIMER_IntGet ( TIMER_TypeDef * timer )

Get pending TIMER interrupt flags.

Note: Event bits are not cleared by this function.

Parameters

[in] timer Pointer to TIMER peripheral register block.

Returns: TIMER interrupt source(s) pending. Returns one or more valid interrupt flags for the TIMER module (TIMER_IF_nnn) OR'ed together.

Definition at line 946 of file em_timer.h .

__STATIC_INLINE uint32_t TIMER_IntGetEnabled ( TIMER_TypeDef * timer )

Get enabled and pending TIMER interrupt flags. Useful for handling more interrupt sources in the same interrupt handler.

Parameters

[in] timer Pointer to TIMER peripheral register block.

Note: Interrupt flags are not cleared by this function.

Returns

Pending and enabled TIMER interrupt sources. The return value is the bitwise AND combination of

the OR combination of enabled interrupt sources in TIMERx_IEN_nnn register (TIMERx_IEN_nnn) and
the OR combination of valid interrupt flags of the TIMER module (TIMERx_IF_nnn).

Definition at line 970 of file em_timer.h .

__STATIC_INLINE void TIMER_IntSet	(	TIMER_TypeDef *	`timer,`
		uint32_t	`flags`
	)

Set one or more pending TIMER interrupts from SW.

Parameters

[in]	`timer`	Pointer to TIMER peripheral register block.
[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.

Definition at line 993 of file em_timer.h .

__STATIC_INLINE void TIMER_Lock ( TIMER_TypeDef * timer )

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

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 function that modifies TIMER registers protected by the lock.

Parameters

[in] timer Pointer to TIMER peripheral register block.

Definition at line 1018 of file em_timer.h .

__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 the TIMER to the same state that it was in after a hardware reset.

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

Parameters

[in] timer A pointer to the TIMER peripheral register block.

Definition at line 389 of file em_timer.c .

__STATIC_INLINE void TIMER_TopBufSet	(	TIMER_TypeDef *	`timer,`
		uint32_t	`val`
	)

Set top value buffer for timer.

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

Parameters

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

Definition at line 1046 of file em_timer.h .

References TIMER_MaxCount() .

__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.

Definition at line 1066 of file em_timer.h .

__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 TIMER to enable writing to locked registers again.

Parameters

Definition at line 1099 of file em_timer.h .

__STATIC_INLINE bool TIMER_Valid ( const TIMER_TypeDef * ref )

Validate TIMER register block pointer.

Parameters

[in] ref Pointer to TIMER peripheral register block.

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