备注
• When the code-security passwords are programmed, all addresses from 0x3F 7F80 to 0x3F 7FF5
cannot be used as program code or data. These locations must be programmed to 0x0000.
• If the code security feature is not used, addresses 0x3F 7F80 to 0x3F 7FEF may be used for code
or data. Addresses 0x3F 7FF0 to 0x3F 7FF5 are reserved for data and should not contain program
code.
表9-6 shows how to handle these memory locations.
