0 Show the current position in the input process data
bin
1 Show the current latch value in the input process data
bin
1 External latch event is enabled (for latch inputs with falling edge, the
bin
terminal saves the current position)
1 External latch event is enabled (for latch inputs with rising edge, the
bin
terminal saves the current position)
ATTENTION: Higher priority than CB1.3 !
