How to Use the Trace Buffer
6.1 Trace View
Use the example program from above and set a break point (e.g. at address
H’000C01A4
) and enter execution
mode. After the CPU has stopped, run the program again (to fill the trace buffer) and then choose View

Trace .
A new window with the content of the trace buffer will open.
6.1.1 Instruction View
This is the instruction view, which shows in the first column the frame number (bus cycle). Note, that the
MB2198-01 Emulator can hold up to 65535 frames (in external mode; 128 frames in internal mode). The second
column shows the internal bus address. The third column shows either the disassembled machine code
(mnemonic) or a data transfer (inclusive data value).
Note that the last executed frame has the number
-1
and all previous frames negative numbers.
The time stamp shows the execution time of the instruction including all internal cycles in nano seconds (billionth
seconds).
Please also note, that in this view the execution frame of the instructions is shown, not their fetch frame.
