IceMASTER DEBUG MODULE (DM)
The iceMASTER Debug Module is a PC based, combination
in-circuit emulation tool and COP8 based OTP/EPROM pro-
gramming tool developed and marketed by MetaLink Corpo-
ration to support the whole COP8 family of products. Na-
tional is a resale vendor for these products.
See Figure 17 for configuration.
The iceMASTER Debug Module is a moderate cost develop-
ment tool. It has the capability of in-circuit emulation for a
specific COP8 microcontroller and in addition serves as a
programming tool for COP8 OTP and EPROM product fami-
lies. Summary of features is as follows:
• Real-time in-circuit emulation; full operating voltage
range operation, full DC-10 MHz clock.
• All processor I/O pins can be cabled to an application de-
velopment board with package compatible cable to
socket and surface mount assembly.
• 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.
• 100 frames of synchronous trace memory. The display
can be HLL source (C source), assembly or mixed. The
most recent history prior to a break is available in the
trace memory.
• Configured break points; uses INTR instruction which is
modestly intrusive.
• Software — 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.
• Debugger software is processor customized, and recon-
figured from a master model file.
• Processor specific symbolic display of registers and bit
level assignments, configured from master model file.
• Halt/Idle mode notification.
• Programming menu supports full product line of program-
mable OTP and EPROM COP8 products. Program data
is taken directly from the overlay RAM.
• Programming of 44 PLCC and 68 PLCC parts requires
external programming adapters.
• Includes wall mount power supply.
• On-board V_PP generator from 5V input or connection to
external supply supported. Requires V_PPlevel adjustment
per the family programming specification (correct level is
provided on an on-screen pop-down display).
• On-line HELP customized to specific processor using
master model file.
• Includes a copy of COP8-DEV-IBMA assembler and
linker SDK.
