Boot ROM
TMS320F28044
Digital Signal Processor
SPRS357A–AUGUST 2006–REVISED OCTOBER 2006
The Boot ROM is factory-programmed with boot-loading software. Boot-mode signals are provided to tell
the bootloader software what boot mode to use on power up. The user can select to boot normally or to
download new software from an external connection or to select boot software that is programmed in the
internal Flash/ROM. The Boot ROM also contains standard tables, such as SIN/COS waveforms, for use
in math related algorithms.
