Here it is ISR

if PIR2.1=1 then
   T3CON=%00000110
   Wp= Wp & uwp
   Xn.0=IN1
   Xn.1=IN2

   
   IF (Xn.0<Xs.0 AND Trf=0) OR  (Xn.0<Xs.0 AND Xn.1=1 AND Trf=1) THEN

@      CLRF _Counter ' and this
          CNT[0]=CNT[0] + Add[0]
      ENDIF
   ENDIF
   
   IF (Xn.1<Xs.1 AND Trf=0) OR (Xn.0<Xs.0 AND Trf=1 AND Xn.1=0) THEN
