2.5.2 HARDWAR
E
PREPARATION
Three
different on-board
modificati
ons
provide the user
with add
itional
flexib
ility
in
using
Monoboard
Microcomputer
1.
Th
ese
modifications
are
described
in
the following
paragraphs.
2.5.2.1
Operation
With/
Without Debug
Module
A wi rewrap socket
(K1
)
is
located
on
the
board
to
configure
Monoboard
Microcomputer
1 for
operation with the EXORciser's
Debug Module
(EXbug
prog ram). When operation
with the
Deb ug
Modul
e is
desired,
the
VUA signal is
supplied
by
the Debug Module
and the jumper connec tions required are shown
in
note
A.
When
the Debug Module
is
not used
,
the
VUA signal
must be the
same as
th
e
VMA signal generated
by the MPU
.
Th
erefore,
the
jumper
connections
required are
shown in
note
B.

2.5.2.2
Operating with External Memory Devices
External
memory
devices
ca
n
be used
in
place of the four on-board
EROM
devices
by
cutting
the
printed circuit wiring
between
terminals
(E1 /E3
and
E2/E4)
on
the board
.
These
terminals
also permit
the
user
to
use jumper wires
to
reconnect
the
circuit for
using the
on-board
EROM
devices
.
This
change is
presented
in
schematic
form
in
note
A
and in
hardware form in note 8
