ZHCSBK1C December 2006 – January 2018 DAC8560
PRODUCTION DATA.
In a normal write sequence, the SYNC line is kept LOW for at least 24 falling edges of SCLK and the DAC is updated on the 24th falling edge. However, if SYNC is brought HIGH before the 24th falling edge, it acts as an interrupt to the write sequence. The shift register is reset, and the write sequence is seen as invalid. Neither an update of the DAC register contents, nor a change in the operating mode occurs, as shown in Figure 69.
