Limits can be 22*4882a593Smuzhiyunset through the Overtemperature Shutdown register and Hysteresis register. The 23*4882a593Smuzhiyunsensor is accurate to 0.5 degree over the range of -25 to +85 C, and to 1.0 24*4882a593Smuzhiyundegree from -40 to +125 C. Resolution of the sensor is 0.0625 degree. The 25*4882a593Smuzhiyunoperating temperature has a minimum of -55 C and a maximum of +150 C. 26*4882a593Smuzhiyun 27*4882a593SmuzhiyunThe TMP102 has a programmable update rate that can select between 8, 4, 1, and 28*4882a593Smuzhiyun0.5 Hz. (Currently the driver only supports the default of 4 Hz). 29*4882a593Smuzhiyun 30*4882a593SmuzhiyunThe driver provides the common sysfs-interface for temperatures (see 31*4882a593SmuzhiyunDocumentation/hwmon/sysfs-interface.rst under Temperatures). 32
