2.5.1.3 MCU Operation Mode
There are two MCU operation modes as follows:
Full Trace Mode
Real-Time Mode
Setting MCU Operation Mode
There are two operation modes: the full trace mode, and the real-time mode. These modes are set using the
[Setup] - [Debug environment] - [Debug environment] menu or the SET RUNMODE command of the
instruction window.
Full Trace Mode
In full trace mode, execution of all the instructions can be traced with no trace data missed. However, when
branching has been performed for three times or more within 11 cycles, getting the trace data will be given a
higher priority, as waits are inserted for MCU, it may not run in real time.
Real time Mode
In real time mode, execution can be performed in the real time of a program. However, when branching has
been performed for three times or more within 11 cycles, some of the trace data may be missed.
In addition, an error may occur during measurement of the cycle count.
