The External Memory Interface is a feature of the
PIC18C601/801 that allows the processor to access
external memory devices, such as FLASH, EPROM,
SRAM, etc. Memory mapped peripherals may also be
accessed.
The External Memory Interface physical implementa-
tion includes up to 26 pins on the PIC18C601 and up to
38 pins on the PIC18C801. These pins are reserved for
external address/data bus functions.

These pins are multiplexed with I/O port pins, but the
I/O functions are only enabled when program execution
takes place in internal Boot RAM and the EBDIS bit in
the MEMCON register is set (see Register 5-1).

Register 5-1 shows the Memory Control Register
(MEMCON). This register contains bits used to control
the operation of the External Memory Interface.
