The F29H850TU boot ROM contains bootloading software that executes every time the device is powered on or reset. Two pins, GPIO72 and GPIO84, are wired to the Boot Select switch (S3). By default, both pins are set HIGH (1) so the device boots from Flash. For more information on the F29H85x boot modes, see the F29H85x, F29P58x, and F29P32x Real-Time Microcontrollers data sheet.
| Boot Mode | GPIO72 (LEFT) | GPIO84 (RIGHT) |
|---|---|---|
| Boot from Parallel GPIO | 0 | 0 |
| Boot from UART/Wait boot | 0 | 1 |
| Boot from CAN | 1 | 0 |
| Boot from Flash (default) | 1 | 1 |
