5.8 Setting Hardware Break Conditions

5.8.1 Setting Hardware Break Conditions
A hardware break causes the user program to stop running a specified number of cycles after a set event or phenomenon is
detected (i.e., a hardware breakpoint is encountered). Up to 16 events can be specified as hardware breakpoint conditions.
5.8.2

Setting Hardware Breakpoints

(1) Setting Hardware Breakpoints
For hardware breakpoints, you can set an OR condition, other condition (AND (Accumulation), AND (Simultaneous),
subroutine, sequential or state transition) and detection of exception events.
The OR condition, other condition and the detection of exception events can be set all at the same time, or only one at a time.
