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.
Command
Operation
Enable Activates breakpOint
and
display regis·
ters for use with go
and
step com·
mands.
Go Initiates
real·time emulation
and
allows
user to specify breakpoints and data
retrieval.
Step
Initiates
emulation in single instruction
Increments.
Each
step is followed by
register dump.
User may
optionally
tailor other diagnostic activity to his
needs.
Interrupt
Emulates user system interrupt.
