20 LM95235 and LM95245 are 11-bit digital temperature sensors with a 2-wire System
21 Management Bus (SMBus) interface and TruTherm technology that can monitor
22 the temperature of a remote diode as well as its own temperature.
23 The chips can be used to very accurately monitor the temperature of
24 external devices such as microprocessors.
26 All temperature values are given in millidegrees Celsius. Local temperature
27 is given within a range of -127 to +127.875 degrees. Remote temperatures are
28 given within a range of -127 to +255 degrees. Resolution depends on
29 temperature input and range.
31 Each sensor has its own critical limit. Additionally, there is a relative
32 hysteresis value common to both critical limits. To make life easier to
33 user-space applications, two absolute values are exported, one for each
34 channel, but these values are of course linked. Only the local hysteresis
35 can be set from user-space, and the same delta applies to the remote
38 The lm95245 driver can change its update interval to a fixed set of values.
39 It will round up to the next selectable interval. See the datasheet for exact
40 values. Reading sensor values more often will do no harm, but will return
