How can I generate Arbitrary PWM with specific pattern on C2834x DSP?

Hello.
I am trying to generate a signal with same width as in figure on 2834x DSP using c2000 support package. Unfortunately ePWm modules CANNOT be used and the only option that I have got are the GPIO pins. I tried repeating sequence stair block and it worked fine When sampling time was 1/(3*140000). However, when decreasing the samplig time to 1/(12*140000), the PWM pin behaviour becomes awkward and the pins is either always ON r always OFF. I tried modifing the step size to be lower value 1/(120*140000), but it also gave this awkward behaviour.

Hi,
Here is an idea:
I set the solver to 0.01step time in above case.
HTH,
