	)

Parameters

fll_id	FLL domain.
frequency	Frequency value to set.
check	Check frequency(with current voltage).

Returns

Set frequency.

void pi_fll_init	(	uint8_t	fll_id,
		uint32_t	frequency
	)

This function initializes an FLL at a given frequency if param is not null.

Parameters

fll_id	FLL domain.
frequency	Initial frequency.
