8.0
The external memory interface allows the device to
access external memory devices (such as Flash,
EPROM, SRAM, etc.) as program or data memory. It is
implemented with 28 pins, multiplexed across four I/O
ports. Three ports (PORTD, PORTE and PORTH) are
multiplexed with the address/data bus for a total of 20
available lines, while PORTJ is multiplexed with the
bus control signals. A list of the pins and their functions
is provided in

As implemented here, the interface is similar to that
introduced on PIC18F8X20 microcontrollers. The most
notable
PIC18F8310/8410 devices supports both 16-Bit and
Multiplexed 8-Bit Data Width modes; it does not sup-
port the 8-Bit Demultiplexed mode. The Bus Width
mode is set by the BW Configuration bit when the
device is programmed and cannot be changed in
software.
The operation of the interface is controlled by the
MEMCON register
bit (MEMCON<7>) enables the interface and disables
the I/O functions of the ports, as well as any other mul-
tiplexed functions. Setting the bit disables the interface
and enables the ports.

modes that use the external memory interface, refer to
