Function Documentation

◆ sl_hfxo_manager_init_hardware()

void sl_hfxo_manager_init_hardware ( void )

HFXO Manager module hardware specific initialization.

◆ sl_hfxo_manager_init()

sl_status_t sl_hfxo_manager_init ( void )

Initialize HFXO Manager module.

Returns: Status Code.

◆ sl_hfxo_manager_update_sleepy_xtal_settings()

sl_status_t sl_hfxo_manager_update_sleepy_xtal_settings ( sl_hfxo_manager_sleepy_xtal_settings_t * settings )

Updates Sleepy Crystal settings.

Parameters

settings Pointer to settings structure

Returns: Status Code.

Note: Those settings are temporarily used to force oscillation on sleepy crystal. Default values should be enough to wake-up sleepy crystals. Otherwise, this function can be used.

◆ sl_hfxo_manager_notify_consecutive_failed_startups()

void sl_hfxo_manager_notify_consecutive_failed_startups ( void )

When this callback function is called, it means that HFXO failed twice in a row to start with normal configurations.

This may mean that there is a bad crystal. When getting this callback, HFXO is running but its properties (frequency, precision) are not guaranteed. This should be considered as an error situation.

◆ sl_hfxo_manager_irq_handler()

void sl_hfxo_manager_irq_handler ( void )

HFXO Manager HFXO interrupt handler.

Note: This function must be called by the HFXO interrupt handler in order to support the HFXO Manager module. This function handles the HFXO_IF_RDY, HFXO_IF_DNSERR and HFXO_XTALCTRL_SKIPCOREBIASOPT interrupt flags.
