HAL_RC_CAL_update_reference_cycle_on_48M_ex()

void HAL_RC_CAL_update_reference_cycle_on_48M_ex	(	uint8_t	lp_cycle,
		int	clear_ave,
		int	ave_window
	)

Get actual frequency of low power RC. The acutal freqency = 48000000 * lp_cycle / ref_cycle.

Parameters

lp_cycle	Target RC cycles to get according reference cycles of 48M crystal clock
clear_ave	clear average counts.
ave_window	average window counts.

Return values

ref_cycle

Cycles of 48000000 crystal clock that equals to lp_cycle
