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 IO pins are ca-

bled 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 IO 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 (eg 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 productsonly supported features are selectable

Tool set integrated interactive symbolic debuggersup-

ports both assembler (COFF) and C Compiler (COD)

SDK linked object formats

Instruction by instruction memoryregister changes dis-

played when in single step operation

Processor specific symbolic display of registers and bit

level assignments configured from master model file

HaltIdle 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 VPP to program parts

Includes a copy of COP8-DEV-IBMA assembler linker
