These chips implement one or two remote and 31one local temperature sensors. Temperature is measured in degrees 32Celsius. Resolution of the remote sensor is 0.0625 degree. Local 33sensor resolution can be set to 0.5, 0.25, 0.125 or 0.0625 degree (not 34supported by the driver so far, so using the default resolution of 0.5 35degree). 36 37The driver provides the common sysfs-interface for temperatures (see 38Documentation/hwmon/sysfs-interface under Temperatures). 39 40The TMP411 and TMP431 chips are compatible with TMP401. TMP411 provides 41some additional features. 42 43* Minimum and Maximum temperature measured since power-on, chip-reset 44 45 Exported via sysfs attributes tempX_lowest and tempX_highest. 46 47* Reset of historical minimum/maximum temperature measurements 48 49 Exported via sysfs attribute temp_reset_history. Writing 1 to this 50 file triggers a reset. 51 52TMP432 is compatible with TMP401 and TMP431. It supports two external 53temperature sensors. 54
