Development Support (Continued)
iceMASTER EVALUATION PROGRAMMING UNIT (EPU)
The iceMASTER EPU-COP880C is a PC based, in-circuit
simulation tool to support the feature family COP8 products.
See Figure 14 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. Program overlay
memory is PC resident; instructions are downloaded over
RS-232 as executed. Approximate performance is
20 kHz.
• Includes a 40 pin DIP cable adapter. Other target pack-
ages are not supported. All processor I/O pins are cabled
to the application development environment.
• Full 32 kbyte of loadable programmable 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 Met-
aLink products — only supported features are selectable.
• Tool set integrated interactive symbolic
debugger — supports both assembler (COFF) and C
Compiler (.COD) SDK linked object formats.
• Instruction by instruction memory/register changes dis-
played when in single step operation.
• Processor specific symbolic display of registers and bit
level assignments, configured from master model file.
• Halt/Idle mode notification. Restart requires special han-
dling.
• Programming menu supports full product line of program-
mable OTP and EPROM COP8 products. Only a 40 ZIF
socket is available on the EPU unit. Adapters are avail-
able for other part package configurations.
• Integral wall mount power supply provides 5V and devel-
ops the required V_PP to program parts.
• Includes a copy of COP8-DEV-IBMA assembler, linker
SDK.
