Legend: (Top of Memory) represents upper boundary of on-chip program memory space (1FFFh for PIC18FX310, 3FFFh
for PIC18FX410). Shaded areas represent unimplemented or inaccessible areas, depending on the mode.
Note 1: This mode is the only available mode on 64-pin devices and the default on 80-pin devices.
2: These modes are only available on 80-pin devices.
