Note:

READ mode

In this mode the master reads the STCN75 slave after setting the slave address (see

Figure 7). 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, TOS and THYS registers), and

● Pointer setting (the pointer has to be set for the register that is to be read)

The temperature register pointer is usually the default pointer.

These modes are shown in the READ mode typical timing diagrams (see Figure 8, Figure 9,

and Figure 10 on page 22).
