Typedef Documentation

nrfx_clock_xo_event_handler_t

typedef void(* nrfx_clock_xo_event_handler_t) (nrfx_clock_xo_event_type_t event)

XO clock event handler.

Parameters

[in]

event

Event.

Enumeration Type Documentation

nrfx_clock_xo_event_type_t

enum nrfx_clock_xo_event_type_t

XO clock events.

Enumerator
NRFX_CLOCK_XO_EVT_HFCLK_STARTED	XO has been started.

Function Documentation

nrfx_clock_xo_init()

int nrfx_clock_xo_init

(

nrfx_clock_xo_event_handler_t

event_handler

)

Function for initializing internal structures in the nrfx_clock_xo module.

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

Parameters

[in]

event_handler

Event handler provided by the user. If not provided, driver works in blocking mode.

Return values

0	The procedure is successful.
-EALREADY	The driver is already initialized.

nrfx_clock_xo_init_check()

bool nrfx_clock_xo_init_check

(

void

)

Function for checking if the clock driver is initialized.

Return values

true	Driver is already initialized.
false	Driver is not initialized.

nrfx_clock_xo_running_check()

NRFX_STATIC_INLINE bool nrfx_clock_xo_running_check

(

nrf_clock_hfclk_t *

p_clk_src

)

Function for checking the XO clock state.

Parameters

[out]

p_clk_src

Pointer to a clock source that is running.

Return values

true	The XO clock is running.
false	The XO clock is not running.
