READING DATA FROM THE AD7993/AD7994
Reading data from the AD7993/AD7994 is a 1-byte or 2-byte
operation. Reading back the contents of the alert status register
or the cycle timer register is a single-byte read operation, as
shown in Figure 29. This assumes the particular register address
has previously been set up by a single-byte write operation to
the address pointer register, as shown in Figure 26. 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 configuration register, conversion result
register, DATAHIGH registers, DATALOW registers, or hysteresis
registers is a 2-byte operation, as shown in Figure 30. The same
rules apply for a 2-byte read as a 1-byte read.
When reading data back from a register on the AD7993 or the
AD7994, for example the conversion result register, if more than
two read bytes are supplied, the same or new data is read from
the AD7993/AD7994 without the need to readdress the device.
This allows the master to continuously read from a data register
without having to readdress the AD7993/AD7994.
