5.9.2. Flash Security Setting Method
The flash security setting method is shown below.
If the input and the release of reset are done after 0x0001 is written in the flash security code area (see
"Figure 3-2 Sector Block Diagram" in "CHAPTER : FLASH MEMORY"), it becomes security ON. If
security is ON once, security does not become OFF without erasing all flash memory area.
