WRITING TO THE AD7414
Depending on the register being written to, there are two
different writes for the AD7414.
Writing to the Address Pointer Register for a subsequent
read.
In order to read data from a particular register, the Ad-
dress Pointer Register must contain the address of that
register. If it does not, the correct address must be written
to the Address Pointer Register by performing a single-
byte write operation, as shown in Figure 5. The write
operation consists of the serial bus address followed by the
address pointer byte. No data is written to any of the data
registers. A read operation is then performed to read the
register.
Writing a single byte of data to the Configuration Regis-
ter, THIGH Register or TLOW Register.
All three registers are 8-bit registers so only one byte of
data can be written to each register. Writing a single byte
of data to one of these registers consists of the serial bus
address, the data register address written to the Address
Pointer Register, followed by the data byte written to the
selected data register. This is illustrated in Figure 6.
READING DATA FROM THE AD7414
Reading data from the AD7414 is a one or two byte op-
eration. Reading back the contents of the Configuration
Register, THIGH Register or TLOW Register is a single byte
read operation as shown in Figure 7. The register address
previously having been set up by a single byte write opera-
tion to the Address Pointer Register. Once the register
address has been set up, any number of reads can be sub-
sequently done from that register without having to write
