TIMEREMLIB

Detailed Description

Timer/Counter (TIMER) Peripheral API.

The timer module consists of three main parts:

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

__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
)

__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.
