CPU Rewrite Mode (Flash Memory Version)
Figure 1.29.1. Flash identification register and flash memory control register 0
Bit 5 of the flash memory control register 0 is a user ROM area select bit which is effective in only boot
mode. If this bit is set to “1” in boot mode, the area to be accessed is switched from the boot ROM area to
the user ROM area. When the CPU rewrite mode needs to be used in boot mode, set this bit to “1”. Note
that if the microcomputer is booted from the user ROM area, it is always the user ROM area that can be
accessed and this bit has no effect. When in boot mode, the function of this bit is effective regardless of
whether the CPU rewrite mode is on or off. Write to this bit only when executing out of an area other than
the internal flash memory.
Bit 6 of the flash memory control register 0 is the program status flag used exclusively to read the operating
status of the auto program operation. If a program error occurs, it is set to “1”. Otherwise, it is “0”.
Bit 7 of the flash memory control register 0 is the erase status flag used exclusively to read the operating
status of the auto erase operation. If an erase error occurs, it is set to “1”. Otherwise, it is “0”.

Note 1: For this bit to be set to “1”, the user needs to write a “0” and then a “1” to it in succession.
Note 2: For this bit to be set to “1”, the user needs to write a “0” and then a “1” to it in succession
Note 3: Effective only when the CPU rewrite mode select bit = 1. After write “1”, write “0” when
Note 4: Write to this bit only when executing out of an area other than the internal flash memory.
0
When it is not this procedure, it is not enacted in “1”. This is necessary to ensure that no
interrupt or DMA transfer will be executed during the interval. Write to this bit only when
executing out of an area other than the internal flash memory. Also only when NMI pin is
“H” level. Clear this bit to “0” after read array command.
when the CPU rewrite mode select bit = “1”. When it is not this procedure, it is not
enacted in “1”. This is necessary to ensure that no interrupt or DMA transfer will be
executed during the interval.
RY/BY status flag is “1”.
