Hi Nima, sorry for the delay, I was on travel again. Here is a small code (I cleaned it from all other tasks) and a screenshot where you can see what is happening. The time between the toggling of GPIO56 and ePWB2B (GPIO3) on CPMB is shorter (4.875 uS) then the one on Period (7.375 uS) Maybe is my equipment? Strange is that the interrupt on ePWM1 does what I expect. (Please visit the site to view this file) I hope, I am the culprit :) Best regards Gustavo
