These chips implements one remote and one local 23temperature sensor. Temperature is measured in degrees 24Celsius. Resolution of the remote sensor is 0.0625 degree. Local 25sensor resolution can be set to 0.5, 0.25, 0.125 or 0.0625 degree (not 26supported by the driver so far, so using the default resolution of 0.5 27degree). 28 29The driver provides the common sysfs-interface for temperatures (see 30/Documentation/hwmon/sysfs-interface under Temperatures). 31 32The TMP411 chip is compatible with TMP401. It provides some additional 33features. 34 35* Minimum and Maximum temperature measured since power-on, chip-reset 36 37 Exported via sysfs attributes tempX_lowest and tempX_highest. 38 39* Reset of historical minimum/maximum temperature measurements 40 41 Exported via sysfs attribute temp_reset_history. Writing 1 to this 42 file triggers a reset. 43
