modified per flash write is one flash word (one line). This limitation follows from the
application of ECC to the flash write operation, see
be performed after following 16 consecutive writes inside the same page. Note that
the erase operation then erases the entire sector.
Remark: Once a page has been written to 16 times, it is still possible to write to other
pages within the same sector without performing a sector erase (assuming that those
pages have been erased previously).

End Sector Number: Should be greater than or equal to start sector number.

PARAM_ERROR
This command must be executed before executing "Copy RAM to flash" or "Erase
Sector(s)" command. Successful execution of the "Copy RAM to flash" or "Erase
Sector(s)" command causes relevant sectors to be protected again. The boot
block can not be prepared by this command. To prepare a single sector use the
same "Start" and "End" sector numbers.
"P 0 0<CR><LF>" prepares the flash sector 0.
