static HAL_StatusTypeDef RCCEx_PLLSAI1_Config	(	RCC_PLLSAI1InitTypeDef *	PllSai1,
		uint32_t	Divider
	)		[static]

Configure the parameters N & P & optionally M of PLLSAI1 and enable PLLSAI1 output clock(s).

Parameters:

PllSai1	pointer to an RCC_PLLSAI1InitTypeDef structure that contains the configuration parameters N & P & optionally M as well as PLLSAI1 output clock(s)
Divider	divider parameter to be updated

Note:

PLLSAI1 is temporary disable to apply new parameters

Return values:

HAL
