On-Chip FLASH Programming API for CodeWarrior Software
ProgramRange programs a range of FLASH memory with the contents of RAM.
This routine doesn’t verify whether the range to be programmed is already
blank. Programming new data to a location that is not blank is not legal. The
resulting value in the FLASH location after such an illegal programming attempt
will be incorrect or unreliable.
ProgramRangeX is the enhanced version of ProgramRange. This function
programs a range of FLASH memory with the contents of RAM. Before
programming, it verifies that the range to be programmed is blank. If the range
is not blank, the function doesn’t attempt to program it (maintaining the integrity
of the range) and returns an error code.
