Thedirection and number of pointer movements are detected.NDF (new data flag) is detected and counted (pointer #1 in virtual concatenation).The differences (delta) between the pointer values of pointers #2 to #4 and pointer #1 aredetermined and recorded (virtual concatenation).using pseudo-random bit sequence PRBS11. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .
