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, 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 8
,
Figure 9
,
and
Figure 10 on page 22
).
