STLM75 Functional description
Doc ID 13296 Rev 12 23/40
3.5 READ mode
In this mode the master reads the STLM75 slave after setting the slave address (see
Figure 8). Following the WRITE mode control bit (R/W
=0) and the acknowledge bit, the word
address 'An' is written to the on-chip address pointer.
There are two READ modes:
● Preset pointer locations (e.g. temperature, T
OS
and T
HYS
registers), and
● Pointer setting (the pointer has to be set for the register that is to be read)
Note: The temperature register pointer is usually the default pointer.
These modes are shown in the READ mode typical timing diagrams (see Figure 9,
Figure 10, and Figure 11).
