is generated. Configuring CompA and CompC the same, it is possible to generate a breakpoint on the third
consecutive occurrence of event M0 without a reset M1.

Scenario 10b shows the case that after M2 then M1 must occur before M0. Starting from a particular point
in code, event M2 must always be followed by M1 before M0. If after any M2, event M0 occurs before
M1 then a trigger is generated.
