Exported_Macros
__LL_TIM_CALC_DEADTIME
Description:
HELPER macro calculating DTG[0:7] in the
TIMx_BDTR register to achieve the requested dead
time duration.
Parameters:
__TIMCLK__: timer input clock frequency (in Hz)
__CKD__: This parameter can be one of the
following values:
LL_TIM_CLOCKDIVISION_DIV1
LL_TIM_CLOCKDIVISION_DIV2
LL_TIM_CLOCKDIVISION_DIV4
__DT__: deadtime duration (in ns)
Return value:
DTG[0:7]
Notes:
ex: __LL_TIM_CALC_DEADTIME (80000000,
LL_TIM_GetClockDivision (), 120);
__LL_TIM_CALC_PSC
Description:
HELPER macro calculating the prescaler value to
