PIC18F97J60 FAMILY
7.1
The operation of the interface is controlled by the
MEMCON register (Register 7-1). This register is
available in all program memory operating modes
except Microcontroller mode. In this mode, the register
is disabled and cannot be written to.
The EBDIS bit (MEMCON<7>) controls the operation
of the bus and related port functions. Clearing EBDIS
enables the interface and disables the I/O functions of
the ports, as well as any other functions multiplexed to
those pins. Setting the bit enables the I/O ports and
other functions, but allows the interface to override
everything else on the pins when an external memory
operation is required. By default, the external bus is
always enabled and disables all other I/Os.

The operation of the EBDIS bit is also influenced by the
program memory mode being used. This is discussed
in more detail in Section 7.5 “Program Memory
Modes and the External Memory Bus”.
The WAIT bits allow for the addition of wait states to
external memory operations. The use of these bits is
discussed in Section 7.3 “Wait States”.
The WM bits select the particular operating mode used
when the bus is operating in 16-Bit Data Width mode.
These operating modes are discussed in more detail in
Section 7.6 “16-Bit Data Width Modes”. The WM bits
have no effect when an 8-Bit Data Width mode is
selected.
