STDS75
Description
The measured temperature value is compared with a temperature limit (which is stored in
the 16-bit (T_OS) READ/WRITE register), and the hysteresis temperature (which is stored in
the 16-bit (T_HYS) READ/WRITE register). If the measured value exceeds these limits, the
OS/INT pin is activated (see Figure 3 on page 8).
