Forum Post: TMS320F28379D: ePWM GPIO and MEP Scalefactor

Part Number: TMS320F28379D Hi Team, When external pullup resistors are added to the ePWM output pins ePWMxA and ePWMxB, both the ePWM outputs are staying low for small amount of time when I initialize GPIO mux for ePWM before the ePWM configurations. Based on the post : https://e2e.ti.com/support/microcontrollers/c2000-microcontrollers-group/c2000/f/c2000-microcontrollers-forum/713586/tms320f28379d-pwm-pins-default-state I changed the sequence to configure ePWM before setting GPIO mux for ePWM. This worked. However, I see that SFO() is not giving a proper output when GPIO is configured after the function is called. SFO() -> GPIO for ePWM -> wrong result GPIO for ePWM -> SFO() -> correct value. I have two questions. 1. How is SFO() dependent on ePWM GPIO configuration? 2. What should be the correct sequence of setting GPIO mux for ePWM? Kind regards, Irene
