Figure 23.7 Data Window Context Menu - Set Trigger A Option
In the Data window, instead of setting a watchpoint, a trigger can be set. Note that only 2
triggers can be set: Trigger A and trigger B. In a general way, the on-chip DBG module
provides combinations of trigger A and trigger B conditions, and according to the number
of triggers defined (one or two), a different trigger DBG Module Mode Setup can be
chosen.
To set a trigger, choose a Set Trigger Address entry and the kind of access - Read, Write,
Read/Write. This sets a trigger at the selected place.
