24.7.3 Predefined channel mode summary
Table 24-129 explains channel double match predefined submode functionality by showing all event sequence possibilities. The initial
state considered for all submodes is channel flags MRLA, MRLB, TDLA and TDLB reset. From initial state one can follow the table
and verify how each submode behaves in a determined sequence of events. Note that the actions performed by an event type depend
on all previous events following the initial state, for a given channel submode.
