TMS320C32 Boot Loader
11-24
The ’C32 boot loader uses the following peripheral memory-mapped registers
as a temporary stack:
- Timer0 counter register (808024h)
- Timer0 period register (808028h)
- DMA0 source address register (808004h)
- DMA0 destination address register (808006h)
- DMA0 transfer counter register (808008h)
These memory-mapped registers are not reset by the boot-loading process.
Before using these peripherals, reprogram these registers with the appropriate
values.
