it is currently written, the bootloader code only moves user code from Flash memory to internal program
memory. This code can easily be modified to add data transfers from Flash memory to X or Y data
memory.
For stand-alone operation, the DSP performs the following steps following a reset with boot mode 9 (boot
from byte wide memory):
6.3
The Flash memory write routine (WR_FLASH) disables the Flash memory software data protection and
then loads one Flash memory sector with data. The Flash memory write code includes a small delay
routine. The delay routine is called at the end of the Flash memory write routine to guarantee that the write
cycle has finished before any other data is loaded to the Flash memory. The Flash memory write routine
is called by the main code as many times as necessary to write the entire user code to the Flash memory
depending how many sectors are required to accommodate the user code.
