CHAPTER2 Dependence Functions
2.1.10.1 Trace Sampling
Trace measurements are made of a program execution status during the interval
between the start and stop of program execution.
■ Trace Sampling
While the trace function is enabled, data is always sampled and recorded in the trace buffer during
execution of an execution command.
The program execution aborts due to a break factor such as a breakpoint, terminating the trace.
Furthermore, when the trace buffer becomes full, a program break can be invoked. This break is called a
trace buffer full break.
■ Frame Number
A number is assigned to each frame of sampled trace data. This number is called a frame number.
The frame number is used to specify the display start position of the trace buffer.
The number 0 is assigned to the last-sampled trace data. Negative values are assigned to trace data that
have been sampled before the arrival at the triggering position.
