Trace Buffer Window
PicTools Manual 3.0
This window shows the contents of the trace buffer memory. It is only available if the
optional
The trace buffer keeps a record of each instruction executed by the emulator. For each
instruction, the record shows the locat ion in the trace buffer, the value of the program
counter, the state of external trace inputs, and the original line of source code.
The trace buffer memory is 16K "deep," resulting in a capacity of approximately 16,384
Microchip instructions . Some instructions, such as JMP and GOTO, take two processor
cycles, and therefore take two locations in the trace buffer memory. In addition, some
TechTools instructions utilize two or three Microchip instructions, and will therefore take
multiple locations in the trace buffer (this is also true of high-level compiled languages,
such as C).
To see the trace buffer window, select Trace from the View menu.
