NOTES:

1. To set this bit to “1”, write “0” and then “1” in succession. Make sure no interrupts will occur before

writing “1” after writing “0”.

Set the microcomputer in read array mode before writing “0” to this bit.

2. To set this bit to “1”, write “0” and then “1” in succession when the FMR01 bit = 1. Make sure no

interrupts will occur before writing “1” after writing “0”.

3. Write to this bit from a program in other than the flash memory.

4. This flag is set to “0” by executing the Clear Status command.

5. Effective when the FMR01 bit = 1 (CPU rewrite mode). If the FMR01 bit = 0, although the FMSTP bit

can be set to “1” by writing “1”, the flash memory is neither placed in low power mode nor initialized.

6. Use the bit process instruction to set the FMR01, FMR02 and FMSTP bits (Refer to “R8C/Tiny Series

Software Manual”.
