The
ICE-49
MCS-48
In-Circuit
Emulator
module
is
an
Intellec-resident
module
that
interfaces with
any
MCS-48
system.
The MCS-48
family consists
of
the 8049, 8048, 8748, 8039, 8035,
and 8021
microcomputers.
The
ICE-49
module
inter-
faces with an
MCS-48 system
through
a cable terminating
in
an
MCS-48
pin-compatible plug
which
replaces the
MCS-48
device
in
the
sytem. With the ICE-49 plug
in
place, the
designer has the capability to
execute
the
system
in
real
time while
collecting
up
to
255
instruction cycles
of real-time trace data.
In
addition,
he can single step the
system
program
to
monitor
more
closely the
program
logic
during execution. Static
RAM
memory
is
available
through the
ICE-49
module
to
emulate MCS-48 program and
data
memory. The designer can
display
and
alter
the
contents
of
data
and replacement
RAM
control
memory,
internal
MCS-48
registers
and
flags
and
I/O
ports.
Powerful
debug
capability
is
extended
into
the
MCS-48 system while ICE-49
debug hardware and software remain inside the
Intellec
system.
Sym-
bolic reference capability
allows the designer
to
use meaningful symbols
rather
than absolute values
when
examining
and
modifying
memory,
registers, flags,
and
I/O
ports
in
this
system.
*EM1 emulator board
is
also required.
