NOTE
• When the code-security passwords are programmed, all addresses between 0x3F 7F80
and 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 through 0x3F 7FEF may
be used for code or data. Addresses 0x3F 7FF0 – 0x3F 7FF5 are reserved for data and
should not contain program code.
Table 3-4 shows how to handle these memory locations.
