Interrupt mode
In Interrupt mode, the OS output first becomes active when the measured temperature
exceeds the T
Configuration register. Once activated, the OS can only be cleared by either putting the
STLM75 into Shutdown mode or by reading from any register (temperature, configuration,
T
when the measured temperature falls below the T
equal to the FT value.
The OS can only be cleared by putting the device into Shutdown mode or reading any
register. Thus, this interrupt/clear process is cyclical between the T
T
the OS/INT pin occur only when the STLM75 is read or placed into Shutdown mode.
Otherwise, OS/INT would remain active independently for any event.
