Figure 36. Center-aligned PWM waveforms (ARR = 8)
Hints on using center-aligned mode:
●
●
TIMx_ARR = 8,
PWM mode is the PWM mode 1,
The output compare flag is set when the counter counts down corresponding to the
center-aligned mode 1 selected for TIM_CMS = 01 in the TIMx_CR1 register.
When starting in center-aligned mode, the current up-down configuration is used. This
means that the counter counts up or down depending on the value written in the
TIM_DIR bit in the TIMx_CR1 register. The TIM_DIR and TIM_CMS bits must not be
changed at the same time by the software.
Writing to the counter while running in center-aligned mode is not recommended as it
can lead to unexpected results. In particular:
