3804 Group (Spec.L)
Parallel I/O Mode
The parallel I/O mode is used to input/output software
commands, address and data in parallel for operation (read,
program and erase) to internal flash memory.
Use the external device (writer) only for 3804 group (Spec.L)
flash memory version. For details, refer to the user’s manual of
each writer manufacturer.
User ROM and Boot ROM Areas
In parallel I/O mode, the User ROM and Boot ROM areas shown
in Figure 81 can be rewritten. Both areas of flash memory can be
operated on in the same way.
The Boot ROM area is 4 Kbytes in size and located at addresses
F00016 through FFFF16. Make sure program and block erase
operations are always performed within this address range.
(Access to any location outside this address range is prohibited.)
In the Boot ROM area, an erase block operation is applied to
only one 4 Kbyte block. The boot ROM area has had a standard
serial I/O mode control program stored in it when shipped from
the factory. Therefore, using the MCU in standard serial I/O
mode, do not rewrite to the Boot ROM area.
