The counter counts up or down depending on the direction bit (DIR). 01: Center-aligned mode 1. The counter counts up and down alternatively. Output compare interrupt flags of channels configured in output (CCxS=00 in TIMx_CCMRx register) are set only when the counter is counting down. 10: Center-aligned mode 2. The counter counts up and down alternatively. Output compare interrupt flags of channels configured in output (CCxS=00 in TIMx_CCMRx register) are set only when the counter is counting up. 11: Center-aligned mode 3.

TIMx_CCR1 preload value is loaded in the active register at each update event. Note: 1: These bits can not be modified as long as LOCK level 3 has been programmed (LOCK bits in TIMx_BDTR register) and CC1S=’00’ (the channel is configured in output). 2: The PWM mode can be used without validating the preload register only in one pulse mode (OPM bit set in TIMx_CR1 register).
