5.5 Using the Event Points
The emulator has the event point function that performs breaking, tracing, and execution time
measurement by specifying more complex conditions along with the PC breakpoints standard for
the High-performance Embedded Workshop.
5.5.1 PC Breakpoints
When the instruction of the specified address is fetched, the user program is stopped. Up to 255
points can be set.
5.5.2 Event Conditions
Event conditions can be used for more complex conditions such as the data condition as well as
specification of the single address.
When the condition is satisfied, event conditions are also used as the start/end conditions for
performance measurement in addition to halting the user program. When event conditions are
used as the start/end conditions for performance measurement, start from setting in the
[Performance Analysis] window.
Several event conditions can be used to set more complex conditions.
Notes: 1. When event conditions are used as the start/end conditions for performance
measurement, step operation cannot be performed. In addition, when execution is
restarted from the address where step operation has been stopped by the
BREAKPOINT, the single step function is used and operation is disabled. Restart
execution after the BREAKPOINT has been canceled.
2. It is not possible to use the break conditions and the start/end conditions for
performance measurement at the same time with one channel. If the performance
measurement start/end conditions are set, the settings of the break conditions will be
disabled.
3. The event conditions that can be set vary according to the emulator in use. For details,
refer to the online help.
