3. Data Latch Control
This block has 4 registers assigned by 2 or 3 bits CODE. DATA is read on the time of up edge of CLK. When STB receivers high signal, DATA in shift register is sent into LATCH to control block which CODE indicates and the operation starts. INPUT TIMING FOR SERIAL DATA When both CLK "H" and DATA "L", STB "H" leads data active.
