输入捕获对寄存器操作怎么用库函数写出来

TIM2->PSC = 0x0;//预分频器
TIM2->ARR = ENCODER_TIM_PERIOD;//设定计数器自动重装值
TIM2->CR1 &=~(3<<8);// 选择时钟分频：不分频
TIM2->CR1 &=~(3<<5);// 选择计数模式:边沿对齐模式
TIM2->CCMR1 |= 1<<0; //CC1S='01' IC1FP1映射到TI1
TIM2->CCMR1 |= 1<<8; //CC2S='01' IC2FP2映射到TI2
TIM2->CCER &= ~(1<<1);    //CC1P='0'    IC1FP1不反相，IC1FP1=TI1
TIM2->CCER &= ~(1<<5);    //CC2P='0'    IC2FP2不反相，IC2FP2=TI2
TIM2->CCMR1 |= 3<<4; // IC1F='1000' 输入捕获1滤波器
TIM2->SMCR |= 3<<0;    //SMS='011' 所有的输入均在上升沿和下降沿有效

这几句对寄存器的操作怎么用库函数写出来？
