SECURITY0 protect &
Reserved (Code option)
Flash ROM mapping
Note: 1. If the code option SECURITY0 = 1 (SECURITY enable), the FLASH ROM ADDRESS = 0x1380 ~ 0x13FF
will not allow to do the “page erase and page program”.
2. If the code option SECURITY0 = 0 (SECURITY disable), the code option address 0x13FC ~ 0x13FF will
not be protected by hardware. And the code option can be “erase and program” by the
in-system-programming function.
