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 specific 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 a hardware breakpoint, you can set an OR condition, other conditions (AND (cumulative), AND (simultaneous),
subroutine, sequential or state transitions) and detection of exceptional events.
For each hardware breakpoint, you can specify all or only one from among the OR condition, other conditions, and detection
of exceptional events.
