SCMECM8 is a real-time in-circuit Emulator dedicated to all Microchip microcontrollers. It is serially linked at 115KBaud to a PC or compatible host and can emulate the microcontroller using either the built-in clock oscillator or any other clock source connected to the microcontroller up to its maximum frequency as specified by Microchip. The system is prepared to run up to 40MHz for supporting future Microchip derivatives. SCMECM8 provides 64Kx16 of code memory with software mapping. Breakpoints allow real-time program execution until an opcode is executed at a specified address. Breakpoints on data values, data read or write and an AND/OR combination of two external signals are also implemented. The MS-Windows software includes source level debugger for C, assembler debugger, performance analyzer, on-line assembler and disassembler, conditional breakpoints and many other features. The SCMECM8 Source Level Debugger includes commands for testing the programs and hardware in real-time. The commands permit setting breakpoints on high-level language lines, adding a watch window with the symbols and variables of interest, modifying variables, showing the trace buffer, executing assembly steps and many more useful functions. Files generated by the most common assemblers and high-level language compilers are accepted by the SCMECM8. Standard systems are supplied with MS-Windows debugger, 128 KBytes of internal memory organized as 64Kx16, 64K hardware breakpoints, real-time trace memory and logic analyzer with external test points.

SCMECM8 accepts files with absolute object or hex format. Assemblers and highlevel languages from leading vendors are supported: Microchip, ByteCraft, Hitech and others.

The SCMECM8 Software includes a Source-Level Debugger. This function may be used to debug code written in Assembler and C. The Source-Level Debugger includes commands which allow the user to get all the information necessary for testing the programs and hardware in real-time.

SCMECM8 uses Microchip bond-out microcontrollers, which are special devices for transparent hardware and software emulation. The selection of a different microcontroller is made by software selection or changing the probe or socket adapter. Following is the list of personality probes and supported devices.

As the list of supported devices and available probes is continuously evolving.

The Personality Probes run at the frequency of the crystal on them or from the clock source supplied by the user hardware. Therefore, the same probe may be adapted to your frequency requirements. The minimum and maximum frequencies are determined by the Microchip bond-out characteristics, but in many cases ’s additional hardware emulates the microcontroller beyond the Microchip bond-out limitations. The Emulator maximum frequency is 40MHz and thus prepared for future devices.

The 32Kx48 Trace Memory is used to record the microprocessor activities.

Eight lines are external test points. Trigger inputs and conditions are available for starting and stopping the trace recording. Frames can be filtered as well as started and stopped with a resolution of a single instruction. The trace buffer can be viewed in disassembled instructions or high level language lines embedded with the related instructions.

This useful function checks the trace buffer and provides time statistics on modules and procedures as a percentage of the total execution time.
