Hi, [quote userid="593630" url="~/support/microcontrollers/c2000-microcontrollers-group/c2000/f/c2000-microcontrollers-forum/1364537/tms320f28388d-power-sequence-of-tms320f28388d"]Because in the datasheet in the PMM block, it seems there is a AND gate for the 3.3V and 1.2V for releasing reset.[/quote] This is correct, reset will not be released until some time after VDD has come up. Best Regards, Ben Collier
