EMULATOR MEMORY
SCMEC51 provides 64KBytes of code memory with software mapping and banking capabilities. DS-51/512K system has a universal memory bank switching configuration for any 32K or 64K banks and up to 32 memory pages.
HARDWARE BREAKPOINTS
Breakpoints allow real-time program execution until an opcode is executed at a specified address. Breakpoints on data read or write and an AND/OR combination of two external signals are also implemented.
CONDITIONAL BREAKPOINTS
A complete set of conditional breakpoints permit halting program emulation on code addresses, source code lines, access to external and on-chip memory, port and register contents.
SOFTWARE ANALYZER
A 64 KByte buffer is used to record any software and hardware events of your program, such as executed code, memory accesses, port and internal register states, external or on-chip data memory contents and more.
LANGUAGES AND FILE FORMATS
SCMEC51 accepts files with many different formats. Assemblers and high-level languages such as C and PLM may be used with DS-51. Supported vendors are Intel, IAR, BSO/Tasking, Keil, Archimedes, 2500AD, MCC, etc.
SOURCE-LEVEL DEBUGGER
The SCMEC51 Software includes a Source-Level Debugger. This function may be used to debug code written in Assembler, PLM 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. The commands permit setting breakpoints on high-level language lines, adding a watch window with the symbols and variables of interest, modifying variables, displaying floating point values, showing the trace buffer, executing assembly steps and many more useful functions.
PERSONALITY PROBES
SCMEC51 uses standard and bond-out microcontrollers for hardware and software emulation. The selection of a different microcontroller is made by replacing the microcontroller on the probe or changing the probe. 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 emulated chip characteristics, while the emulator maximum frequency is 42MHz.
TRACE AND LOGIC ANALYZER
The 32 KBytes trace memory is used to record the microprocessor activities. Eight lines are user selectable test points. Trigger inputs and conditions are available for starting and stopping the trace recording. The trace buffer can be viewed in disassembled instructions or high-level language lines embedded with the related instructions. The trace window may be displayed on the fly, thus without stopping the emulation.

SCMEC51 WINDOWS DEBUGGER
SCMEC51 is supplied with a Source-Level Debugger and Simulator for the 8051 architecture. The program allows fast and reliable debugging at source-level for PLM, C and Assembler of most of the available vendors. The Debugger may be operated with or without the SCMEC51 Emulator. Together with DS-51, the software executes all functions in real-time. The debugger may be used as a stand-alone simulator to test software without hardware, although not in real-time and at a speed depending on your PC.
The Debugger includes an On-line Assembler, which can be invoked to change the executable code during the debugging session. As the Debugger is fully MS-Windows oriented, multiple windows and multi-tasking are permitted.
GLOBAL AND LOCAL MENUS
A Global Menu lists the commands and is accessible through a menu bar that runs along the top of the window. From there, pull-down menus are available for every item on the menu bar. The Debugger is context-sensitive and uses Local Menus tailored to the particular window you are in.
INPUT BOXES
Many of the Windows Debugger Command Options are available in Input Boxes. An Input Box prompts you to type in a string. All your entries are recorded in a History Buffer, so you can pick up any entry just by selecting it with the arrow keys.
STATUS LINE
The Status Line on the bottom of the main application window displays messages related to the cursor position in the Module window, chip type, operating mode (simulation, emulation or in-circuit simulation) and current status (program running, ready, error). It also provides on-line help information on selected menus.
TRACE OPTIONS
A selection of source code, disassembled instruction or mixed source and disassembled code is available to display the Trace Memory without stopping the emulation. Time Stamps can be used to display absolute or relative cycles or time. Filters may be defined to specify instructions or sequences of interest. The software also has the capability to save the trace buffer in a disk file.
EXTERNAL TRACE START/STOP TRIGGERS
SCMEC51 has two External Trigger signals that allow starting and stopping of the trace recording upon external events.
Stop Trace when Full or Continuous Recording Mode
There are two trace recording modes: Cyclic and Trace Full. In the Cyclic Mode the trace is continuously filled with recorded data. In the Full Mode recording stops when trace is full.
Selectable Trace Trigger Levels
The trigger state permits selecting the way trigger signals behave. The active mode may be either level or edge for the external start and stop trigger signals.
Trace Status on the Fly
Trace Status allows viewing information without stopping emulation. The Trace Status includes buffer full, buffer empty, length, etc.
Trace Filtering on Address Ranges
Up to 10 different ranges are allowed to filter the recorded data into the trace memory. The start and stop addresses of modules and procedures can be entered using special prefixes.
Trace Trigger Conditions
The bus cycle type, address and data bus contents are used to trigger the trace collection. Trace triggers recognize user-defined events, such as cycles, address matches and passcounts. A cycle specifies the execution state. The address match selects the address value or range. Addresses can be entered as symbols, modules and line numbers or as physical addresses.
Passcount selects the number of times the event will be recognized before the trace trigger occurs.
BREAKPOINT OPTIONS
SCMEC51 commands let Breakpoints be displayed, set and cleared. The different options are used to stop the emulation upon execution of simple events as well as combinations of complex hardware and software conditions. The program may be halted according to a selection of cycle type, address match condition, address range and passcount.
Breakpoint on Data Read/Write and Address
Real-time Hardware Breakpoints can be set on Data Read, Data Write, Data Read or Write and Opcode Fetch in any address range.
Stop Emulation on Passcount
Passcount on any event including opcode may be specified by the number of occurrences.
Breakpoint on External Events
Trace Testpoints may be used as External Breakpoints on hardware events if enabled. The External Breakpoint Triggers may also be used as a Trace Full Condition; in this case, program execution will stop once it is full. The Logic Operator Commands allow selection of AND/OR combinations of the two External Breakpoints. The options are both low, any one is low, both are high, only one is high, both are leading edge, etc.
Expression True Global
The Expression True Global Command allows setting a breakpoint that will occur when the value of the specified memory space location matches the specified data value.
Change Memory Global
This command may be used to set a breakpoint on access to any specified memory space, regardless of the data contents.
PERFORMANCE ANALYZER
This function processes the information recorded in the trace buffer and provides a graphics representation of the executed modules and the percentage of time spent in each of them. The local menu of this window may be used to get more useful information about software performance.
Configuration
A dialog box allows the function selection belonging to the module that may be included in the performance analysis; thus, the performance analyzer may be configured according to the relevant parameters.
Real-Time Analysis
The window may be refreshed with the new data accumulated in the trace buffer without stopping the emulation.
Software Information
The Performance Analyzer provides all the relevant information related to a selected software module in the window.
PERSONALITY PROBES
Probe C51 and C51LV and C591

Therefore, you may use the same probe for many derivatives just by replacing the microcontroller on the probe. The maximum frequency of this probe is related to emulation mode and it is 20MHz to 33MHz, although it may change according to the innovations of the microcontrollers and derivatives. Both the probe and the emulator are prepared to run up to 42MHz. Probe C51LV has an optional 64K data memory that can be mapped to the emulator and accessed by MOVX instructions and supports 3V and 5V, as well as 6 clocks / cycle microcontrollers such as 89C51RD2.

The emulation header supplied with this probe is:
Emulation Header Description
H-550-44P 44-pin PLCC
Probe C752
This personality probe supports the 8xC750/1/2 and 8xC748/9 microcontrollers by using a standard 87C752 with the security bits programmed. This probe has a XTAL Jumper that allows selecting the clock source from the crystal on the probe or from an external source.
The crystal on the probe is mounted on a socket and may also be replaced by any other one within the frequency range specified by the emulated microcontroller. While selecting the chip type 8xC749 or 8xC752 from the software menu, the AVcc and AVss signals are rerouted to the target board and should be connected to the appropriate voltages in order to use Port 1.
Probe C752 uses a standard 87C752 operating in emulation mode to emulate 8xC748 and 8xC750/1 microcontrollers. The main software difference between both types of chips is found in the Interrupt Enable Register (IE -address A8h). The ETI bit of the IE Register has different addresses. The 87C752 locates the ETI bit at bit address ADh, while 8xC748 and 8xC750/1 chips have that bit at address ABh.
Therefore, when emulating an 8xC748 or 8xC750/1 with 87C752, the assembler or high-level language compiler must be set up so that the target chip is an 8xC752 to generate the file for the emulator. Once software
debugging is complete, the target chip must be redefined and recompiled to to generate the file for the 8xC748 or 8xC750/1 programmer.
The above manipulations are only necessary if the software is using the ETI register bit for an 8xC750/1. The 8xC748 is equivalent to the 8xC750 and the 8xC749 is equivalent to the 8xC752. Frequency is limited by the 87C752 operating in emulation mode. Probe C752 comes with two emulation headers, 28-pin DIP and 24-pin DIP.
Adapters for 28-pin PLCC are also available.
