STM32F407VGT6定时器1PWM输出

这个PWM输出我一直没能实现，使用其他定时器都实现了，请各位高手帮忙看看，稍后我会把代码贴出来。

void TIM1_Init(void)
{
  RCC->AHB1ENR |=(1<<4);
GPIOE->MODER |=0x08000000;
GPIOE->OSPEEDR |=0x0C000000;
GPIOE->PUPDR |=0x04000000;

GPIOE->AFR[1] |=0x00100000;
RCC->APB2ENR |=(1<<0);
TIM1->PSC=167;
TIM1->ARR=999;
TIM1->EGR |=1;

TIM1->CCMR2 |=0x0060;
TIM1->CCMR3 |=0000;
TIM1->CCMR2 |=0x0008;
TIM1->BDTR |=1<<15;
TIM1->CR1 |=1;
}
该函数没有PWM波形产生
