Hi Peter, Thanks for your reply. Let me double check: 1. That means if I don't disable pullup all GPIOs in application code, it will keep pullup enable? That means if I don't use such this code ( GpioCtrlRegs . GPAPUD . all = 0x0000 ;) , that's will be fine? ) [quote userid="450338" url="~/support/microcontrollers/c2000-microcontrollers-group/c2000/f/c2000-microcontrollers-forum/1453315/tms320f28022-q1-is-gpio-pin-must-to-enable-pullup/5575499#5575499"]all GPIOs have internal pullup enabled by default at reset except AIOs (which don't have internal pullup circuitry) and EPWM-capable pins.
