I am new to this device and blocks associated with it and I have read the block description page. I am trying to do some ADC in and PWM outs. But for all the examples the ePWM blocks are orange and with an input port of "WA", however if I drag the exactly same block from the library the block will not have any input port even if all the settings are the same. I believe the input is to drive the ePWM clock.
Please help me, the image is attached below.
