The external interface offers the designer the flexibility to place external devices in almost
any range of the 24-bit address space. The primary hardware consideration is that more
chip selects are available in high memory and devices needing more than 15 Wait states
must use one of chip selects CS[2–5]. Once a design is completed, it is necessary to
develop software for it. The task of designing application software is much easier if the
hardware designer considers the following guidelines:
•
The microcontroller’s internal Flash must be enabled during software development.
This simplifies downloading of program code and allows the ZDS II default program
configuration to be used. If the internal Flash is disabled, the address space beginning
at
option bits, vectors, and application startup code.

higher priority for addresses 000000H
through 00FFFFH.
Stack and Data is pla ced anywhere in
CS1 address space except where
higher priority CS2 or CS3 overlaps.
Unused addresses as no
memory placed in these locations.
Ethernet MAC is an example of an
external communication peripheral that
is connected to the external interface.
CAN controller is another example of
an external communication peripheral
that is conn ected to the
interface.
Unused addresses as no
