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.
