Figure 13-18. PSCr behavior versus PSCr Input A in Mode 3
PSCR Input A is taken into account during DT0 and OT0 only. It has no effect during DT1 and OT1.
When PSCR Input A event occurs, PSCR releases PSCOUTr0, jumps and executes DT1 plus OT1 plus
DT0 while PSCR Input A is in active state.
Even if PSCR Input A is released during DT1 or OT1, DT1 plus OT1 sub-cycle is always completely
executed.
Figure 13-19. PSCr behavior versus PSCr Input B in Mode 3
PSCR Input B is taken into account during DT1 and OT1 only. It has no effect during DT0 and OT0.
When PSCR Input B event occurs, PSCR releases PSCOUTR1, jumps and executes DT0 plus OT0 plus
DT1 while PSCR Input B is in active state.
Even if PSCR Input B is released during DT0 or OT0, DT0 plus OT0 sub-cycle is always completely
executed.
