FLASH MEMORY VERSION
19.4 Flash memory parallel I/O mode
19.4 Flash memory parallel I/O mode
In the flash memory parallel I/O mode, the contents of the user ROM area and boot ROM area can be
reprogrammed by using a dedicated parallel programmer. (See Figure 19.1.2.) About the parallel programmer
concerned, consult its manufacturer, and for more information on using it, refer to the user’s manual of the
parallel programmer.
In the flash memory parallel I/O mode, the boot ROM area is assigned to addresses 016 to 1FFFF16 (word
addresses).
Note that if the boot ROM area has been reprogrammed in the flash memory parallel I/O mode, the flash
memory serial I/O mode cannot be used. (Refer to section “19.3 Flash memory serial I/O mode.”)
Also, addresses FF9016 to FF9F16 (the user ROM area) are reserved for serial and parallel programmers. Therefore,
besure not to use this area.
