Flash Memory Parallel I/O Mode
The flash memory parallel I/O mode is used to manipulate the inter-
nal flash memory with a parallel programmer. This parallel program-
mer uses the software commands listed in Table 1 to do the flash
memory manipulations, such as read/programming/erase opera-
tions.

User ROM Area and Boot ROM Area
The user ROM area and boot ROM area can be reprogrammed in
the flash memory parallel I/O mode.
The programming and block erase operations can be performed only
to these areas.
The boot ROM area, 8 Kbytes in size, is assigned to addresses
000016–1FFF16, so that programming and block erase operations
can be performed only to this area. (Access to any address out of
this area is prohibited).
The erasable block in the boot ROM area is only one block, consist-
ing of 8 Kbytes. The reprogramming control firmware to be used in
the flash memory serial I/O mode has been stored to this boot ROM
area on our shipment. Therefore, do not reprogram the boot ROM
area if the user uses the flash memory serial I/O mode.
Do not program to addresses FF9016 to FF9F16 because this area is
the reserved area for the programmer.
Note that, when the boot ROM area is read out from the CPU in the
CPU reprogramming mode, described later, its addresses will be
shifted to E00016—FFFF16.
Addresses FF9016 to FF9F16 are the reserved area for the parallel
programmer. Therefore, when the user uses the flash memory paral-
lel I/O mode, do not program to this area.
