READING DATA
Reading data from the ADT75 is done in a one data byte operation for the configuration register and a two data byte operation for the
temperature value register, T
Figure 17. Reading back the contents of the temperature value register is shown in Figure 18. Reading back from any register first requires
a single-byte write operation to the address pointer register to set up the register address of the register that is going to be read from. To
read from another register, execute another write to the address pointer register to set up the relevant register address. Thus, block reads are
not possible, that is, there is no I
that is going to receive a read command then there is no need to repeat a write operation to set up the register address again.
