Development Support
iceMASTER EVALUATION PROGRAMMING UNIT (EPU)
The iceMASTER EPU-COP888GG is a PC based in-circuit
simulation tool to support the feature family COP8 products
See Figure 21 for configuration
The simulation capability is a very low cost means of evalu-
ating the general COP8 architecture In addition the EPU
has programming capability with added adapters for pro-
gramming the whole COP8 product family of OTP and
EPROM products The product includes the following fea-
tures
Non-real-time in-circuit simulation
memory is PC resident instructions are downloaded over
RS-232 as executed
20 kHz
Includes a 40-pin DIP cable adapter Other target pack-
ages are not supported All processor I O pins are ca-
bled to the application development environment
Full 32 kbytes of loadable programming space that over-
lays (replaces) the on-chip ROM or EPROM On-chip
RAM and I O blocks are used directly or recreated as
necessary
On-chip timer and WATCHDOG execution are not well
synchronized to the instruction simulation
100 frames of synchronous trace memory The display
can be HLL source (e g C source) assembly or mixed
The most recent history prior to a break is available in the
trace memory
Up to eight software configured break points uses INTR
instruction which is modestly intrusive
Common look-feel debugger software across all Meta-
Link products only supported features are selectable
Approximate performance is
