Note:
Interrupt mode
In Interrupt mode, the OS/INT output first becomes active when the measured temperature
exceeds the T
configuration register. Once activated, the OS/INT can only be cleared by either putting the
STTS75 into shutdown mode or by reading from any register (temperature, configuration,
