Counter overflow/underflow, Setting the UG bit
or Update generation through the slave mode
controller generates an update request
Only counter overflow/underflow generates an
update request
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);
