PIC18F85J11 FAMILY
6.1.4
By default, devices in Extended Microcontroller mode
directly present the program counter value on the
external address bus for those addresses in the range
of the external memory space. In practical terms, this
means addresses in the external memory device below
the top of on-chip memory are unavailable.

EXTENDED MICROCONTROLLER
MODE AND ADDRESS SHIFTING
(Top of Memory) represents upper boundary of on-chip program memory space (see Figure 6-1 for device-specific
values). Shaded areas represent unimplemented, or inaccessible areas, depending on the mode.
This mode is the only available mode on 64-pin devices and the default mode on 80-pin devices.
These modes are only available on 80-pin devices.

To avoid this, the Extended Microcontroller mode
implements an address shifting option to enable auto-
matic address translation. In this mode, addresses
presented on the external bus are shifted down by the
size of the on-chip program memory and are remapped
to start at 0000h. This allows the complete use of the
external memory device’s memory space.
