CBC是cycle by cycle.触发后的动作只在一个PWM周期有效,在下一个开关周期开始的时候会自动清除标志位。如果故障状态还存在再次触发,如果不存在PWM正常工作。
If the cycle-by-cycle trip
event is still present when the CBC bit is cleared, then CBC will be immediately set again. The
specified condition on the pins is automatically cleared when the ePWM time-base counter
reaches zero (TBCTR = 0x0000) if the trip condition is no longer present. The condition on the
pins is only cleared when the TBCTR = 0x0000 no matter where in the cycle the CBC flag is
cleared.
这一段是在ti的pdf里找到的,请问这里的pins是什么意思啊? 是不是要先设置pins脚的功能,由这个pins而引发事件啊?谢谢!
