ON-CHIP REGISTERS
The AD7715 contains four on-chip registers, which can be
accessed by via the serial port on the part. The first of these
is a communications register that decides whether the next
operation is a read or write operation and also decides which
register the read or write operation accesses. All communi-
cations to the part must start with a write operation to the
communications register. After power-on or RESET, the
device expects a write to its communications register. The data
written to this register determines whether the next operation
to the part is a write or a read operation and also determines to
which register this read or write operation occurs. Therefore,
write access to any of the other registers on the part starts with
a write operation to the communications register followed by a
write to the selected register. A read operation from any register
on the part (including the communications register itself and
the output data register) starts with a write operation to the
communications register followed by a read operation from the
selected register. The communication register also controls the
standby mode and the operating gain of the part. The DRDY status
is also available by reading from the communications register. The
second register is a setup register that determines calibration
modes, filter selection and bipolar/unipolar operation. The
third register is the data register from which the output data
from the part is accessed. The final register is a test register
that is accessed when testing the device. It is advised that the
user does not attempt to access or change the contents of the
test register as it may lead to unspecified operation of the
device. The registers are discussed in more detail in the
following sections.
