下面这种代码，后面这个\是什么意思啊？
#define IS_TIM_ALL_PERIPH(PERIPH) (((PERIPH) == TIM1) || \
                                 ((PERIPH) == TIM2) || \
                                 ((PERIPH) == TIM3) || \
                                 ((PERIPH) == TIM4) || \
                                 ((PERIPH) == TIM5) || \
                                 ((PERIPH) == TIM6) || \
                                 ((PERIPH) == TIM7) || \
                                 ((PERIPH) == TIM8) || \
                                 ((PERIPH) == TIM9) || \
                                 ((PERIPH) == TIM10)|| \
                                 ((PERIPH) == TIM11)|| \
                                 ((PERIPH) == TIM12)|| \
                                 ((PERIPH) == TIM13)|| \
                                 ((PERIPH) == TIM14)|| \
                                 ((PERIPH) == TIM15)|| \
                                 ((PERIPH) == TIM16)|| \
