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.
