NOTE A: Boot ROM: If the boot ROM is enabled, then addresses 0000−00FF in the program space will be occupied by boot ROM.

† Addresses 0040h−0043h in program memory are reserved for code security passwords.

‡ When CNF = 1, addresses FE00h−FEFFh and FF00h−FFFFh 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 FE00h−FEFFh are referred to as reserved.

§ When CNF = 0, addresses 0100h−01FFh and 0200h−02FFh 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 0100h−01FFh are referred to as reserved.

¶ Addresses 0300h−03FFh and 0400h−04FFh 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 0400h−04FFh are referred to as reserved.
