CLB 模块干预PWM输出问题

Other Parts Discussed in Thread: C2000WARE

你好,在技术手册中有如下描述:

(1) PWMA[OE] and PWMB[OE] refer to trip outputs from the respective PWM module.(2) PWMA[AQ] and PWMB[AQ] refer to the output of the AQ submodule in the respective PWM module.(3) PWMA[DB] and PWMB[DB] refer to the output of the DB submodule in the respective PWM module.

除此之外就看不到CLB模块和ePWM模块关联关系的详细描述了。这里的ePMW AQ/OE/DB究竟是指ePWM AQ/DB子模块中的哪些寄存器,CLB干预这些ePWM模块后的输出效果是什么?

简单介绍一下我的应用背景:

CLB模块在电机控制器中应用,正常情况下,PWM信号由C28核根据调制方式给出,但在故障触发后,希望CLB辨识出故障信号,并能够接管PWM输出的控制,对PWM输出进行封锁。所以不知道以目前的CLB输出关系的设计,这样的用途是否能够实现?或者能够有更详细的关于CLB模块与PWM输出的关联关系描述?

谢谢!
