READ mode
In this mode the master reads the STCN75 slave after setting the slave address (see
Figure
address 'An' is written to the on-chip address pointer.
There are two READ modes:
●
●
The temperature register pointer is usually the default pointer.
These modes are shown in the READ mode typical timing diagrams (see
