6. Trace

How to Use the Trace Buffer

Trace function displays addresses and instructions executed so far. While execution of a program, the address,
data and status information can be sampled and stored in the trace buffer. This function is called real-time trace.

In-depth analysis of a program execution history can be performed using the data recorded by real-time trace.
