Output control
Output is controlled by truth table right side.
Setting the shift direction of shift-register
L : reverse side shift (SO
→
SI), H : forward side shift (SI
→
SO)
LAT data Input
L : The data of shiftregister is transferred to ouput latch.
H : The ouput data of latch is holded.
Serial clock Input Down-side edge trigger
