NOTE A: Boot ROM: If the boot ROM is enabled, then addresses 000000FF in the program space will be occupied by boot ROM.
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.
