5. Debugging Functions
Specifiable conditions vary with the trace mode, as summarized in the tables below.
1. Fill until stop
The trace memory can hold up to 4-M bus cycles. When the buffer becomes full, the oldest data among the acquired trace
information are overwritten with new data. The emulator continues acquiring trace information in this way until the
program is stopped.

2. Fill until full
Once the trace memory of the emulator overflows during trace acquisition, the emulator stops acquiring trace information.

3. Fill around TP
Trace acquisition is halted a specified number of cycles after a trace point is encountered. In this mode, the user program
continues running and only trace acquisition is halted. Sophisticated conditions can be set using a maximum of 16 event
points. The delay value can be chosen as 0M, 1M, 2M, 3M or 4M cycles.

4. Repeat fill until stop
For each time trace point encountered, information for a total of 512 cycles before and after that point is acquired, and
acquisition continues in the same way until the program stops running. Acquisition continues until it is halted by a break or
forced stop. The positions where trace points have been encountered can be checked in the Trace window.
