This bit indicates the operation status of the flash memory. The bit is “0” during programming, erasing,
or erase-suspend mode; otherwise, the bit is “1”.
The microcomputer enables to acknowledge commands by setting the FMR01 bit to “1” (CPU rewrite
mode). To set this bit to “1”, it is necessary to set to “1” after first setting to “0”. Set this bit to “0” by only
writing “0”.
The combined setting of the FMR02 bit and the FMR16 bit enable to program and erase in the user
ROM area. See Table 17.5.2.1 for setting details. To set this bit to “1”, it is necessary to set to “1” after
first setting to “0”. Set this bit to “0” by only writing “0”. This bit is enabled only when the FMR01 bit is
“1” (CPU rewrite mode enable).
This bit resets the flash memory control circuits and minimizes power consumption in the flash
memory. Access to the flash memory is disabled when the FMSTP bit is set to “1”. Set the FMSTP bit
by a program in a space other than the flash memory.
Set the FMSTP bit to “1” if one of the following occurs:
Figure 17.5.1.3 shows a flow chart illustrating how to start and stop the flash memory before and after
entering low power mode. Follow the procedure on this flow chart.
To enter stop or wait mode when CPU rewrite mode is disabled, do not set the FMR0 register. The
flash memory is automatically turned off when entering and turned back on when exiting.
This is a read-only bit indicating an auto-program operation status. This bit is set to “1” when a pro-
gram error occurs; otherwise, it is set to “0”. For details, refer to 17.8.4 Full Status Check.
This is a read-only bit indicating an auto-erase operation status. The bit is set to “1” when an erase
error occurs; otherwise, it is set to “0”. For details, refer to 17.8.4 Full Status Check.
