一、SOCSEL选择SOC触发源时为什么updowm模式可以有TBPRD或ZERO(SOCASEL=011B),那不是一个PWM周期产生两个SOC。因为updowm模式TBPRD或ZERO不是同一个时间。
二、手册还说Enable event time-base counter equal to zero or period is useful in up down count mode。useful 体现在哪里啊。
1.对的,一个周期触发两次;
2.请指明一下这句话的出处:
Enable event time-base counter equal to zero or period is useful in up down count mode
您好,非常感谢。那句话出自ETSE寄存器的表格SOCASEL成员描述里面。SOCASEL=011B时的描述就是这句话。按您的提示,useful应该就是指能产生两次SOC了。
