STM32H7用hal库编程，使用定时器的编码器模式采集光栅尺的信号，一运行程序中断会有异常，没有计数就会进入更新中断，还会连续进入两次

运行结果及报错内容

调试的时候将断点放在中断void TIM4_IRQHandler(void)函数内部会直接进入，但是定时器的CNT没有变化，没有计数，一步一步调试会不断进入中断，Encoder_Overflow_Count有变化，去掉断点后，Encoder_Overflow_Count变化一会后就停止了

我的解答思路和尝试过的方法

中断函数改成了现在的，以前是在HAL_TIM_PeriodElapsedCallback(),内部写的，一样的现象。
改过IO的初始化和编码器模式的初始化，不知道是不是初始化的问题，目前没能解决。

我想要达到的结果

怎么能计数到一定值才进入更新中断呢，不想一开始不断进入中断。

报的错内容是什么啊

编译后没有报错，程序一启动就会不断进入编码器模式相应的定时器的更新中断，然后里边的程序就会运行，记录溢出次数的变量就会变化，导致在中断服务函数里什么都干不了
