3.1.8 Boot Modes

The F280039C boot ROM contains bootloading software that executes every time the device is powered on or reset. Two pins, GPIO24 and GPIO32, are wired to the Boot Select switch (S3). By default, both pins are set HIGH (1) so the device will boot from Flash. For more information on the F28003x boot modes, see the TMS320F28003x Real-Time Microcontrollers Data Sheet.
