mpsl_init()

int32_t mpsl_init	(	mpsl_clock_lfclk_cfg_t const *	p_clock_config,
		IRQn_Type	low_prio_irq,
		mpsl_assert_handler_t	p_assert_handler
	)

#include <mpsl/include/mpsl.h>

MPSL initialization.

Parameters

[in]	p_clock_config	Clock configuration. If NULL the LF clock will be configured as an RC source with rc_ctiv = MPSL_RECOMMENDED_RC_CTIV, .rc_temp_ctiv = MPSL_RECOMMENDED_RC_TEMP_CTIV, and .accuracy_ppm = MPSL_DEFAULT_CLOCK_ACCURACY_PPM.
[in]	low_prio_irq	IRQ to pend when low priority processing should be executed. The application shall call mpsl_low_priority_process after this IRQ has occurred.
[in]	p_assert_handler	Pointer to MPSL assert handler.

Note

If CONFIG_SYSTEM_CLOCK_NO_WAIT is set to 0, never modify the SEVONPEND flag in the SCR register, while this function is executing. Doing so might lead to a deadlock.

If only Front End Module functionality is needed, Initialization API of MPSL FEM can be called instead.

Return values

0	MPSL is successfully initialized.
-NRF_EPERM	MPSL is already initialized.
-NRF_EINVAL	Invalid parameters supplied.
