Summary description

7/37

The measured temperature value is compared with a temperature limit (which is stored in

the 16-bit (TOS) READ/WRITE register), and the hysteresis temperature (which is stored in

the 16-bit (THYS) READ/WRITE register). If the measured value exceeds these limits, the

OS/INT pin is activated (see Figure 3 on page 8).
