TIMER_PRSSEL_TypeDef#

typedef uint8_t TIMER_PRSSEL_TypeDef

Peripheral Reflex System signal.

TIMER_Valid#

bool TIMER_Valid (const TIMER_TypeDef * ref)

Validate the TIMER register block pointer.

Returns

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

TIMER_SupportsDTI#

bool TIMER_SupportsDTI (const TIMER_TypeDef * ref)

Check whether the TIMER is valid and supports Dead Timer Insertion (DTI).

Returns

• True if ref points to a valid timer that supports DTI, false otherwise.

TIMER_MaxCount#

uint32_t TIMER_MaxCount (const TIMER_TypeDef * ref)

Get the Max count of the timer.

Returns

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

TIMER_CaptureGet#

uint32_t TIMER_CaptureGet (TIMER_TypeDef * timer, unsigned int ch)

Get compare/capture value for the compare/capture channel.

Returns

• Current capture value.

TIMER_CaptureBufGet#

uint32_t TIMER_CaptureBufGet (TIMER_TypeDef * timer, unsigned int ch)

Get the buffered compare/capture value for compare/capture channel.

Returns

• Current buffered capture value.

TIMER_CompareBufSet#

void TIMER_CompareBufSet (TIMER_TypeDef * timer, unsigned int ch, uint32_t val)

Set the compare value buffer for the compare/capture channel when operating in compare or PWM mode.

The compare value buffer holds the value which will be written to TIMERn_CCx_CCV on an update event if the buffer has been updated since the last event.

TIMER_CompareSet#

void TIMER_CompareSet (TIMER_TypeDef * timer, unsigned int ch, uint32_t val)

Set the compare value for compare/capture channel when operating in compare or PWM mode.

TIMER_CounterGet#

uint32_t TIMER_CounterGet (TIMER_TypeDef * timer)

Get the TIMER counter value.

Returns

• Current TIMER counter value.

TIMER_CounterSet#

void TIMER_CounterSet (TIMER_TypeDef * timer, uint32_t val)

Set the TIMER counter value.

TIMER_Enable#

void TIMER_Enable (TIMER_TypeDef * timer, bool enable)

Start/stop TIMER.

TIMER_Init#

void TIMER_Init (TIMER_TypeDef * timer, const TIMER_Init_TypeDef * init)

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.

TIMER_InitCC#

void TIMER_InitCC (TIMER_TypeDef * timer, unsigned int ch, const TIMER_InitCC_TypeDef * init)

Initialize the TIMER compare/capture channel.

Notice that if operating the channel in compare mode, the CCV and CCVB register must be set separately, as required.

TIMER_InitDTI#

void TIMER_InitDTI (TIMER_TypeDef * timer, const TIMER_InitDTI_TypeDef * init)

Initialize the TIMER DTI unit.

TIMER_EnableDTI#

void TIMER_EnableDTI (TIMER_TypeDef * timer, bool enable)

Enable or disable DTI unit.

TIMER_GetDTIFault#

uint32_t TIMER_GetDTIFault (TIMER_TypeDef * timer)

Get DTI fault source flags status.

Note

• Event bits are not cleared by this function.

Returns

• Status of the DTI fault source flags. Returns one or more valid DTI fault source flags (TIMER_DTFAULT_nnn) OR'ed together.

TIMER_ClearDTIFault#

void TIMER_ClearDTIFault (TIMER_TypeDef * timer, uint32_t flags)

Clear DTI fault source flags.

TIMER_IntClear#

void TIMER_IntClear (TIMER_TypeDef * timer, uint32_t flags)

Clear one or more pending TIMER interrupts.

TIMER_IntDisable#

void TIMER_IntDisable (TIMER_TypeDef * timer, uint32_t flags)

Disable one or more TIMER interrupts.

TIMER_IntEnable#

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.

TIMER_IntGet#

uint32_t TIMER_IntGet (TIMER_TypeDef * timer)

Get pending TIMER interrupt flags.

Note

• Event bits are not cleared by this function.

Returns

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

TIMER_IntGetEnabled#

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.

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).

TIMER_IntSet#

void TIMER_IntSet (TIMER_TypeDef * timer, uint32_t flags)

Set one or more pending TIMER interrupts from SW.

TIMER_Lock#

void TIMER_Lock (TIMER_TypeDef * timer)

Lock some TIMER registers 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.

TIMER_Reset#

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.

TIMER_TopBufSet#

void TIMER_TopBufSet (TIMER_TypeDef * timer, uint32_t val)

Set the top value buffer for the 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.

TIMER_TopGet#

uint32_t TIMER_TopGet (TIMER_TypeDef * timer)

Get the top value setting for the timer.

Returns

• Current top value.

TIMER_TopSet#

void TIMER_TopSet (TIMER_TypeDef * timer, uint32_t val)

Set the top value for timer.

TIMER_Unlock#

void TIMER_Unlock (TIMER_TypeDef * timer)

Unlock TIMER to enable writing to locked registers again.

TIMER_INIT_DEFAULT#

#define TIMER_INIT_DEFAULT

Default configuration for TIMER initialization structure.

TIMER_INITCC_DEFAULT#

#define TIMER_INITCC_DEFAULT

Default configuration for TIMER compare/capture initialization structure.

TIMER_INITDTI_DEFAULT#

#define TIMER_INITDTI_DEFAULT

Default configuration for TIMER DTI initialization structure.
