Cautions When Using Flash Memory
This section explains the cautions when using the Flash memory.
−
If this device is reset during the write, the data that is written cannot be guaranteed.
Moreover, It is necessary to prevent an unexpected reset like Watchdog Timer from occurring during
the writing and erasing.
−
Immediately after issuing the automatic algorithm command to the flash memory, always perform a
dummy read before reading the flash status register.
−
If the device is forced to transfer to the low-power consumption mode, ensure the operations of the
flash memory automatic algorithm is completed.
See chapter "Low Power Consumption Mode" in "FM0+ Family Peripheral Manual" for details on the
low-power consumption mode.
