TI中文支持网你们好，
我现在用F28069的TZ故障。当正常时，TZ信号为高电平，有PWM输出；当TZ信号为低电平时PWM一直关闭。我想做成发生TZ触发后PWM关闭10S后，如果TZ信号正常了，PWM可以有输出。也即怎么让TZ出发后，然后TZ故障消除了，停上10S再启动。

请问您的问题具体是什么？不是太明白。

mangui zhang：结合复位信号在硬件上实现触发后同时进行复位
有一些复位芯片通过电容大小可以做到一定的延时

请问一下老师，这个TZ的触发方式在TMS320F28027芯片里写死了吗？是只能低电平触发吗

是的,手册里有说明
The trip-zone signals at pins TZ1 to TZ6 (also collectively referred to as TZn) are active low input signals.
