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 will have the same effect as a write to FF00h. For simplicity, addresses FE00h–FEFFh are referred to as reserved
when CNF = 1.
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 will have 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 illegal.
NOTE A: There is no external memory space for program, data, global data, or I/O in the ’C242. The GREG register is reserved in the ’C242.
