#define __LL_LPUART_DIV	(		__PERIPHCLK__,
			__BAUDRATE__
	)

Value:

(uint32_t)(((((uint64_t)(__PERIPHCLK__)*LPUART_LPUARTDIV_FREQ_MUL) + (uint32_t)((__BAUDRATE__)/2U))/(__BAUDRATE__))\
                                                                & LPUART_BRR_MASK)

Compute LPUARTDIV value according to Peripheral Clock and expected Baud Rate (20-bit value of LPUARTDIV is returned)

Parameters:

__PERIPHCLK__	Peripheral Clock frequency used for LPUART Instance
__BAUDRATE__	Baud Rate value to achieve

Return values:

LPUARTDIV

value to be used for BRR register filling
