Part Number:TMS320F28027
We are developing a brushless motor tool and want to configure the PWM module. During the normal motor operation, we can configure one software PWM signal at the high side and turn off one PWM signal at low side. But right now we want to turn on all of three low side PWM signals when any one software PWM signal at the high side is low. For example, the PWM duty cycle is 75%, when the PWM signal in one high side is low during 25% of PWM period, we want to turn on all of three low side PWM signals. I can't find the function in doc "TMS320x2802x, 2803x Piccolo Enhanced PulseWidth Modulator (ePWM) Module Reference Guide". I am not sure that the TI PWM module can support the function above. If yes, can you provide me a datasheet or example code?
Thanks
