READING DATA FROM THE AD7992
Reading data from the AD7992 is a 1- or 2-byte operation.
Reading back the contents of the alert status register, the config-
uration register, or the cycle timer register is a single-byte read
operation, as shown in Figure 28. This assumes the particular
register address has previously been set up by a single-byte write
operation to the address pointer register (see Figure 25). Once
the register address has been set up, any number of reads can
be performed from that particular register without having to
write to the address pointer register again. If a read from a
different register is required, the relevant register address has
to be written to the address pointer register, and again any
number of reads from this register may then be performed.
Reading data from the conversion result register, DATAHIGH
registers, DATALOW registers, or hysteresis registers is a 2-byte
operation, as shown in Figure 29. The same rules apply for a
2-byte read as a 1-byte read.
When reading data back from a register, such as the conversion
result register, if more than two read bytes are supplied, the
same or new data is read from the AD7992 without the need to
re-address the device. This allows the master to continuously
read from a data register without having to re-address the
AD7992.
