Serial Data Interface
The serial-in data (DAI) will be clocked into 8 bit shift register synchronized on the rising edge
of the clock (DCK). The data ‘1’ represents the corresponding current output ‘ON’, while the data
‘0’ stands for ‘OFF’. The data will be transferred into the 8 bit latch register when the strobe signal
(LAT) is ‘H’ (level trigger); otherwise, the data will be held. The trigger timing of the serial-out data
(DAO) will be shifted out on synchronization to the rising edge of the clock. All outputs are turned
off while enable terminal (EN) is kept at high level. And they are active when EN shifts to low.
