Scrolling and the scroll count

The following describes signal processing during scrolling:

<< Scroll signal processing >>

“+1 count” (If the transition of PT3A precedes that of PT3B)

(PT3A, PT3B) = (0,0) → (1,0) → (1,1) or (PT3A, PT3B) = (1,1) → (0,1) → (0,0)

“−1 count” (If the transition of PT3B precedes that of PT3A)

(PT3A, PT3B) = (0,0) → (0,1) → (1,1) or (PT3A, PT3B) = (1,1) → (1,0) → (0,0)

PT3A : PT3B

0 : 0

PT3A : PT3B

1 : 1

0 : 1

1 : 0
