ICE-49
Cable Card
The
cable card
is
included
for cable
driving.
It
transmits
address and
data bus
information
to the user
system
through
a
40-pin connector which plugs
into the user
system
in
the socket designed
for the
MCS-48
device.
Software
The
ICE-49 software
driver
is
a
RAM-based
program
which
provides the user with
an easy
to
use
command
language
(see Table
1,
Table
2,
and Table
3)
for
defining
breakpoints,
initiating real-time emulation or single
step
operation, and
interrogating
and
altering user
system
status recorded during emulation.
The
ICE-49
command
language contains
a
broad range
of modifiers
to
provide
the
user with
maximum
flexibility
in
defining the opera-
tion to be performed. The
ICE-49 software
driver
is
available
on
diskette
and
operates
in
32K
of Intellec
RAM
memory.

with
go and
step
com-
mands.
Initiates real-time emulation and
allows
user
to specify breakpoints and
data
retrieval.
Initiates
emulation
in
single instruction
increments. Each
step
is
followed by
register
dump.
User
may
optionally
tailor
other diagnostic
activity to his
needs.
