S12S Debug Module (S12SDBGV2)
S12SDBGV1 SCR encoding because OR possibilities are very limited in the channel encoding. By adding
OR forks as shown in red this scenario is possible.

SCR1=1101

On simultaneous matches the lowest channel number has priority so with this configuration the forking
from State1 has the peculiar effect that a simultaneous match0/match1 transitions to final state but a
simultaneous match2/match1transitions to state2.

Scenario 8
Trigger when a routine/event at M2 follows either M1 or M0.

Scenario 8a and 8b are possible with the S12SDBGV1 and S12SDBGV2 SCR encoding
