Detailed Description

Macro Definition Documentation

__LL_SWPMI_CALC_BITRATE_PRESCALER

#define __LL_SWPMI_CALC_BITRATE_PRESCALER	(		__FSWP__,
			__FSWPCLK__ )

Value:

((uint32_t)(((__FSWPCLK__) / ((__FSWP__) * 4)) - 1))

Helper macro to calculate bit rate value to set in BRR register (LL_SWPMI_SetBitRatePrescaler function).

Note

ex: __LL_SWPMI_CALC_BITRATE_PRESCALER(2000000, 80000000);

Parameters

__FSWP__	Within the following range: from 100 Kbit/s up to 2Mbit/s (in bit/s)
__FSWPCLK__	PCLK or HSI frequency (in Hz)

Return values

Bitrate

prescaler (BRR register)
