C. Flash Protection for Invalid Erase/Write



Overview

This is example to prevent changing code or data in flash by abnormal operation(noise, unstable power,

malfunction, etc…).



How to protect the flash

•

Divide into decision and execution to Erase/Write in flash.

Check the program sequence from decision to execution in order of precedence about Erase/Write.

Setting the flags in program and check the flags in main loop at the end

When the Flash Erase/Write is executed, check the flags. If not matched, do not execute.

•

Check the range of Flash Sector Address

If the flash sector address is outside of specific area, do not execute.

•

Use the Dummy Address

Set the flash sector address to dummy address in usually run time.

Change the flash sector address to real area range shortly before Erase/Write.

Even if invalid Erase/Write occurred, it will be Erase/Write in dummy address in flash.

•

Use the LVR/LVI

Unstable or low powers give an adverse effect on MCU. So use the LVR/LVI
