mpsl_clock_ctrl_source_register()

int32_t mpsl_clock_ctrl_source_register	(	const mpsl_clock_lfclk_ctrl_source_t *	p_lfclk_ctrl_source,
		const mpsl_clock_hfclk_ctrl_source_t *	p_hfclk_ctrl_source )

#include <mpsl/include/mpsl_clock.h>

Register an external clock driver.

When this API is called, MPSL will use an external clock driver instead of the built-in clock driver.

Note

The API must be called before mpsl_init() to enable MPSL use external clock driver.

The API is supported for nRF54h series. It is experimental for nRF52, nRF53 series.

Parameters

[in]	p_lfclk_ctrl_source	A pointer to struct holding the API to LFCLK control.
[in]	p_hfclk_ctrl_source	A pointer to struct holding the API to HFCLK control.

Note

Any of the clock control pointers can't be NULL. In such case the function return -NRF_EINVAL.

Return values

0	Clock control API is successfully registered.
-NRF_EPERM	Clock control API is already initialized.
-NRF_EINVAL	Invalid parameters supplied.
