[参考译文] TMS320F280025C：需要在发生跳闸事件时进行&quot；同步&quot；PWM (重置时基计数器)

https://e2e.ti.com/support/microcontrollers/c2000-microcontrollers-group/c2000/f/c2000-microcontrollers-forum/1158064/tms320f280025c-need-to-sync-pwm-reset-time-base-counter-on-trip-event

这是 SysConfig 附带的一些代码。  

我让 PWM 使用 CMPSS2进行逐周期限制。 这一切都是令人震惊的。  

我有跳闸5信号进入 CLB。 在 CMPSS2信号进入后10微秒内使用状态和计数器生成脉冲。 该脉冲路由到 trip8、后者路由到 PWM3数字比较模块。 根据我看到的情况、设置应该允许跳闸8生成一个将复位 TIEM 基址计数器的"SYNC"信号。  

它不是。 我不明白为什么。 我尝试使用 EVTA1和 EVTB1作为源。 满足我的需求

想法？
