RE ADING FROM AND WRIT ING T O T HE ON-CHIP RE GIST E RS
T he AD7730 contains a total of thirteen on-chip registers. T hese registers are all accessed over a three-wire interface. As a result,
addressing of registers is via a write operation to the topmost register on the part, the Communications Register. Figure 5 shows a
flowchart for reading from the different registers on the part summarizing the sequence and the words to be written to access each of
the registers. Figure 6 gives a flowchart for writing to the different registers on the part, again summarizing the sequence and words
to be written to the AD7730.
