† Each even-numbered shift register stage takes on the state of the next-lower even-numbered stage, and likewise each odd-numbered shift
register stage takes on the state of the next-lower odd-numbered stage; i.e., R32 takes on the state of R30, R30 takes on the state of R28, ...
R4 takes on the state of R2, R2 takes on the state of DATA IN2, R31 takes on the state of R29, R29 takes on the state of R27, ... R3 takes on
the state of R1, and R1 takes on the state on DATA IN1.
‡ New data enters the latches while LATCH ENABLE is high. This data is stored while LATCH ENABLE is low.
