1. After the power is turned on and the voltage is stabilized, LCK should be activated, after clocking 12 data bits
into the DATA terminal.
2. Qx parallel output data of the shift register is set after the 12th clock by the LCK.
3. Since the LCK is a label latch, data is retained in the Lsection and renewed in the Hsection of the LCK.
4. Data retained in the internal latch circuit is output when the OE is in the Lsection.
