When the FMR01 bit in the FMR0 register is set to 1 (CPU rewrite mode enabled), the MCU enters CPU
rewrite mode and software commands can be accepted. At this time, the FMR02 bit in the FMR0 register is set
to 0 so that EW0 mode is selected.
Software commands are used to control program and erase operations. The FST register can be used to confirm
whether programming or erasure has completed.
To enter erase-suspend during auto-erasure, set the FMR20 bit to 1 (erase-suspend enabled) and the FMR21 bit
to 1 (erase-suspend request). Wait for td(SR-SUS) and ensure that the FST6 bit in the FST register is set to 1
(during erase-suspend) before accessing the flash memory. Auto-erasure can be restarted by setting the FMR21
bit in the FMR2 register to 0 (erase restart).
After the FMR01 bit in the FMR0 register is set to 1 (CPU rewrite mode enabled), EW1 mode is selected by
setting the FMR02 bit is set to 1.
The FST register can be used to confirm whether programming and erasure has completed.
To enable the erase-suspend function during auto-erasure, execute the block erase command after setting the
FMR20 bit in the FMR2 register to 1 (suspend enabled). To enter erase-suspend while auto-erasing the user
ROM area, set the FMR22 bit in the FMR2 register to 1 (erase-suspend request enabled by interrupt request).
Also, the interrupt to enter program-suspend must be enabled beforehand.
When an interrupt request is generated, the FMR21 bit in the FMR2 register is automatically set to 1 (erase-
suspend request) and auto-erasure suspends after td(SR-SUS). After interrupt handling completes, set the
FMR21 bit to 0 (erase restart) to restart auto-erasure.
