  13Description
  14-----------
  15
  16The ADT7410 is a temperature sensor with rated temperature range of -55°C to
  17+150°C. It has a high accuracy of +/-0.5°C and can be operated at a resolution
  18of 13 bits (0.0625°C) or 16 bits (0.0078°C). The sensor provides an INT pin to
  19indicate that a minimum or maximum temperature set point has been exceeded, as
  20well as a critical temperature (CT) pin to indicate that the critical
  21temperature set point has been exceeded. Both pins can be set up with a common
  22hysteresis of 0°C - 15°C and a fault queue, ranging from 1 to 4 events. Both
  23pins can individually set to be active-low or active-high, while the whole
  24device can either run in comparator mode or interrupt mode. The ADT7410
  25supports continous temperature sampling, as well as sampling one temperature
  26value per second or even justget one sample on demand for power saving.
  27Besides, it can completely power down its ADC, if power management is
  28required.

  30Configuration Notes
  31-------------------
  32
  33Since the device uses one hysteresis value, which is an offset to minimum,
  34maximum and critical temperature, it can only be set for temp#_max_hyst.
  35However, temp#_min_hyst and temp#_crit_hyst show their corresponding
  36hysteresis.
  37The device is set to 16 bit resolution and comparator mode.
