Hi, I am using F2812 chip to implement the following. 1- Generate a symmetric three phase PWM, PWM7-12, using EVB on chip. 2- Map the compare match 4, CMP4, to call a software Interrupt service routine using PIE. The first task, PWM generation, was successfully done. I have verified the physical hardware output using a scope. However, for the second part, compare match Interrupt, I couldn?t
