#define __LL_USART_DIV_SAMPLING16	(		__PERIPHCLK__,
			__BAUDRATE__
	)		(((__PERIPHCLK__) + ((__BAUDRATE__)/2U))/(__BAUDRATE__))

Compute USARTDIV value according to Peripheral Clock and expected Baud Rate in 16 bits sampling mode (32 bits value of USARTDIV is returned)

Parameters:

__PERIPHCLK__	Peripheral Clock frequency used for USART instance
__BAUDRATE__	Baud rate value to achieve

Return values:

USARTDIV

value to be used for BRR register filling in OverSampling_16 case
