Typedef Documentation

typedef void(* nrfx_clock_event_handler_t)(nrfx_clock_evt_type_t event)

Clock event handler.

Parameters

[in] event Event.

Enumeration Type Documentation

enum nrfx_clock_evt_type_t

Clock events.

Enumerator
NRFX_CLOCK_EVT_HFCLK_STARTED	HFCLK has been started.
NRFX_CLOCK_EVT_LFCLK_STARTED	LFCLK has been started.
NRFX_CLOCK_EVT_CTTO	Calibration timeout.
NRFX_CLOCK_EVT_CAL_DONE	Calibration has been done.

Function Documentation

nrfx_err_t nrfx_clock_calibration_start ( void )

Function for starting the calibration of internal LFCLK.

This function starts the calibration process. The process cannot be aborted. LFCLK and HFCLK must be running before this function is called.

Return values

NRFX_SUCCESS	The procedure is successful.
NRFX_ERROR_INVALID_STATE	The low-frequency of high-frequency clock is off.
NRFX_ERROR_BUSY	Clock is in the calibration phase.

void nrfx_clock_calibration_timer_start ( uint8_t interval )

Function for starting calibration timer.

Parameters

[in] interval Time after which the CTTO event and interrupt will be generated (in 0.25 s units).

__STATIC_INLINE bool nrfx_clock_hfclk_is_running ( void )

Function for checking the HFCLK state.

Return values

true	The HFCLK is running (XTAL source).
false	The HFCLK is not running.

nrfx_err_t nrfx_clock_init ( nrfx_clock_event_handler_t event_handler )

Function for initializing internal structures in the nrfx_clock module.

After initialization, the module is in power off state (clocks are not started).

Parameters

[in] event_handler Event handler provided by the user. Must not be NULL.

Return values

NRFX_SUCCESS	The procedure is successful.
NRFX_ERROR_ALREADY_INITIALIZED	The driver is already initialized.

nrfx_err_t nrfx_clock_is_calibrating ( void )

Function for checking if calibration is in progress.

This function indicates that the system is in calibration phase.

Return values

NRFX_SUCCESS	The procedure is successful.
NRFX_ERROR_BUSY	Clock is in the calibration phase.

__STATIC_INLINE bool nrfx_clock_lfclk_is_running ( void )

Function for checking the LFCLK state.

Return values

true	The LFCLK is running.
false	The LFCLK is not running.

__STATIC_INLINE uint32_t nrfx_clock_ppi_event_addr ( nrf_clock_event_t event )

Function for returning a requested event address for the clock driver module.

Parameters

[in] event One of the peripheral events.

Returns: Event address.

__STATIC_INLINE uint32_t nrfx_clock_ppi_task_addr ( nrf_clock_task_t task )

Function for returning a requested task address for the clock driver module.

Parameters

[in] task One of the peripheral tasks.

Returns: Task address.
