This function assumes CCER has 1 bit per timer, but on this MCU, each timer has 4 bits. Function should have this layout instead:
static void TIM_CCxChannelCmd(TIM_TypeDef *TIMx, uint32_t Channel, uint32_t ChannelState)
{
uint32_t tmp;
/* Check the parameters */
assert_param(IS_TIM_CC1_INSTANCE(TIMx));
assert_param(IS_TIM_CHANNELS(Channel));
tmp = TIM_CCER_CC1E << (Channel & 0x03U)*3;
/* Reset the CCxE Bit */
TIMx->CCER &= ~tmp;
/* Set or reset the CCxE Bit */
TIMx->CCER |= (uint32_t)(ChannelState << (Channel & 0x03U)*3);
}
