Parallel I/O Mode
User ROM and Boot ROM Areas
The parallel I/O mode can be used to input and output the software commands, addresses and data needed to operate
(read, program, erase, etc.) the internal flash memory. In this mode, the M30245 (flash memory version) operates in a
manner similar to other flash memory from Renesas. Because there are some differences with some functions not
available with the microcomputer and the memory capacity, the M30245 cannot be programmed by a programmer for
other Renesas flash memory. Use an exclusive programmer that supports the M30245 (flash memory version). Refer
to the instruction manual of each programmer manufacturer for usage details.
In parallel I/O mode, the user ROM and boot ROM areas shown in Figure 1.149 can be rewritten. Both areas of flash
memory can be operated on in the same way.
Program and block erase operations can be performed in the user ROM area. The user ROM area and it's blocks are
shown in Figure 1.149.
The boot ROM area is 8 Kbytes in size. In parallel I/O mode, it is located at addresses 0FE000
Ensure that the 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 8 Kbyte block. The boot ROM area has a standard
serial I/O mode control program installed at the Renesas factory, therefore, it is unnecessary to write to the boot ROM
area when using standard serial I/O mode.
