Hi team,
As we are looking to migrate from TM4C123x to the TM4C129x, we see that on the TM4C129x device, no longer does PB[3:2] (or any other pins) have I2C0 as its default function upon POR. We are looking to use I2C0 to load the flash from the boot loader. How do we set the PB[3:2] pins to be I2C0 if they do not default set as I2C0 functionality upon POR if there is nothing in flash? Does that mean that I2C0 cannot be used to load the flash?
