Addresses 0040h0043h in program memory are reserved for code security passwords.
When CNF = 1, addresses FE00hFEFFh and FF00hFFFFh are mapped to the same physical block (B0) in program-memory space. For
example, a write to FE00h has the same effect as a write to FF00h. For simplicity, addresses FE00hFEFFh are referred to as reserved.
§ When CNF = 0, addresses 0100h01FFh and 0200h02FFh are mapped to the same physical block (B0) in data-memory space. For example,
a write to 0100h has the same effect as a write to 0200h. For simplicity, addresses 0100h01FFh are referred to as reserved.
Addresses 0300h03FFh and 0400h04FFh are mapped to the same physical block (B1) in data-memory space. For example, a write to 0400h
has the same effect as a write to 0300h. For simplicity, addresses 0400h04FFh are referred to as reserved.
