Clear Status Register
In CPU rewrite mode, the user ROM area can be rewritten when the CPU executes software commands.
The user ROM area can be rewritten with the microcomputer mounted on a board, without using a parallel
or serial programmer.
Write the rewrite control program to either the user ROM area or the boot ROM area, beforehand. No
program in the flash memory can be executed in CPU rewrite mode. Therefore, transfer rewrite control
program to an area other than flash memory (internal RAM, etc.), and execute.
CPU rewrite mode can be entered when the microcomputer is in single-chip, memory expansion, and boot
mode.
Software commands, listed in Table 25.3, can be used in CPU rewrite mode. Refer to 25.3.3 Software
Command for details of each command.
