__LL_RCC_CALC_PCLK2_FREQ macro

Helper macro to calculate the PCLK2 frequency (ABP2)

Syntax

#define __LL_RCC_CALC_PCLK2_FREQ(__HCLKFREQ__, __APB2PRESCALER__) ((__HCLKFREQ__) >> APBPrescTable[(__APB2PRESCALER__) >> RCC_CFGR_PPRE2_Pos])

HCLK frequency

This parameter can be one of the following values: @arg LL_RCC_APB2_DIV_1 @arg LL_RCC_APB2_DIV_2 @arg LL_RCC_APB2_DIV_4 @arg LL_RCC_APB2_DIV_8 @arg LL_RCC_APB2_DIV_16

PCLK2 clock frequency (in Hz)
