Texas Instruments MSP50C614 manual ±26. Trace Mode

Software Emulator

Trace Mode : This menu option launches the Trace Mode Dialog (Figure 5±25), that allows that user to run the chip in trace mode, i.e., running an internal program on the chip while monitoring its execution on the scanport.

This radio button is checked when trace mode is running.

Start tracing.

Stop tracing.

Exit Trace Mode

Optional Trace Mode start program memory location (hex). If this value is not provided, execution starts from current PC value.

Optional PC location where execution should stop. If ªStop Afterº field is used, program stops which ever occurs first.

Optional number of clock cycles to execute from Start location. If ªStop at PCº field is used, program stops which ever occurs first.

Saves the result of trace to a file with the name as project with extension .trc.

Run Internal : This menu option launches execution on the program actually programmed on the chip. In the case of MSP50P614/MSP50C614, program execution will stop if a hardware breakpoint is encountered. Otherwise, the user will have to stop execution by hitting the Stop icon, for example. IMPORTANT: The hardware breakpoint has to be located more that one cycle away from the current program counter location. For example, if the current PC is 0x0800, and the instruction at 0x0800 is a one cycle instruction (like NOP), then the closest location for a hardware breakpoint is at PC+2. If a breakpoint was set at address PC+1, it would be ignored by the system. NOTE: The code to execute must be present on the chip.
