In the MCU mode, user-created programs can rewrite the data memory of FLASH in
page (64 bytes) units. (It can be used to save application last keys and preset data.)
In the serial PROM mode, it is possible to perform serial writing to the data memory of
FLASH in the same manner as for the program memory. So, initial values can be
factory-set in the data memory of FLASH.
Using support programs incorporated in the BOOT-ROM makes it easy to write to the
FLASH.
