CONFIGURING THE AD7715
The AD7715 contains three on-chip registers which the user
accesses via the serial interface. Communication with any of
these registers is initiated by writing to the communications
register first. Figure 10 outlines a flow chart of the sequence
which is used to configure all registers after a power-up or reset.
The flowchart also shows two different read options—the first
where the DRDY pin is polled to determine when an update of
the data register has taken place, the second where the DRDY
bit of the communications register is interrogated to see if a
data register update has taken place. Also included in the
flowing diagram is a series of words which should be written
to the registers for a particular set of operating conditions.
These conditions are gain of 1, no filter sync, bipolar mode,
buffer off, clock of 2.4576 MHz, and an output rate of 60 Hz.
