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.

as the register contents would remain the same since they are only changed by a
