Hi, I want to do phase shifting using complementary output at Timer1 using CH1 and CH1N. I believe it can be done using CCR2 register.

MX_TIM1_Init();

 /* USER CODE BEGIN 2 */

 RCC->APB2ENR |= RCC_APB2ENR_TIM1EN; // Enable timer1

 //RCC->APB1ENR |= RCC_APB1ENR_TIM3EN;

 TIM1->CCMR1 |= 0x0000E8E8; // CH1 & CH2 Output Compare(CC1S), Preload(OC1PE), PWM1 Enable(OC1M)*

 TIM1->CCMR2 |= 0x000000E8; // CH3 Output Compare(CC3S), Preload(OC3PE), PWM1 Enable(OC3M)*

 TIM1->CCER |= 0x00000555; // complementary output enable CH1,CH3

 TIM1->CR1 |= 0x000000A1;  // Centre Align Mode 1 & Counter Enable Auto-reload Preload enable

 TIM1->CR2 |= 0x00000045; // CCPC:1(Update CCxE,CCxNE,OCxM for event, OC1Ref: trigger output)

 TIM1->ARR = 266;    

 TIM1->CCR1 = 133; // 50% Duty cycle

 TIM1-> CCR2 = 53;

 TIM1->CCR3 = 133;

 TIM1->BDTR |= 0x00008800; // Enable Main O/P & Enable OSSR
