Table 5.14 Trace modes
Stop mode
1 Fill until stop
2 Fill until full
3 Fill around TP
4 Repeat fill until stop
5 Repeat fill until full
CAUTION
Recording is made in units of total 512 cycles, consisting of 1 cycle at the line where a trace point is met and 255 cycles before
that point and 256 cycles after that point.
Figure 5.49 Differences between the trace modes
Specifiable conditions vary depending on trace mode, as summarized in the table below.

Description
Trace acquisition continues until the program stops running.
Trace acquisition stops when the trace memory is filled.
Trace acquisition stops a specified number of cycles after a
trace point is encountered. A delay value can be specified in
a range of up to the maximum value of trace capacity.
Each time a trace point is encountered, acquisition is made
for a total of 512 cycles* before and after that point, and
acquisition continues that way until the program stops
running.
