When LATCH is "H", the DATA signal is forced "L" internally.
The read decision for the DATA signal (SI) is made by the signal when the CLOCK signal rises.
The read decision for the LATCH signal (SI) is made by the signal when the LATCH signal itself rises.
A "L" must follow at the end of each signal to wait for the next signal.
