Standalone Mode
After power-on, write 1001 to the control word to disable daisy-
chain mode. The first falling edge of SYNC resets a counter that
counts the number of serial clocks, ensuring the correct number
of bits are shifted in and out of the serial shift registers. A rising
edge on SYNC during a write causes the write cycle to be aborted.
After the falling edge of the 16th SCLK pulse, data is auto-
matically transferred from the input shift register to the DAC.
For another serial transfer to take place, the counter must be
reset by the falling edge of SYNC.
