Strange pauses during PWM pulse generation
For motor control, I use 2 PWM modules. Within a test routine, I produce 100 Hz pulses with lengths from 1 to 100 %. But from time to time (around every 10 to 20 secs) pulse generation stops for around 100 mS on both channels. In parallel the GPIO Dir11 is toggled. This output is continous. There are no interrupts or other activities running.
Attached you will find a snapshot from the logic analyzer and the sample project.
Because I have no idea what the reason for that behavior is, so I need the advice of experts.
