3.1.114 testThermoQ
Name
testThermoQ—verifies the generation of an interrupt by the temperature sensor device. The
current temperature is read, and then a high limit, which is less than the current temperature,
is set. This immediately causes the device to report an over-temperature condition through its
configuration register and its interrupt out line. Following a successful high limit test, the
thermostat is placed in a quiescent state, with limits of –55 and +125, and the interrupts
disabled. This prevents further high temperature interrupts from being generated.
This test can be run under conditions of stable or gradually changing board temperature.
Interrupt generation is verified.
Note: This test can only be run if the board is kept between 0 and 70 degrees Celsius. Outside
that range, writes to the non-volatile memory of the ds1621 are not allowed, so the thermal
limits cannot be set, and the test fails.
