It senses the +temperature of a single external diode. The high limit is +theoretically defined as 85 or 100 degrees C through a combination +of external resistors, so the user cannot change it. Values seen so +far suggest that the two possible limits are actually 95 and 110 +degrees C. The datasheet is rather poor and obviously inaccurate +on several points including this one. + +All temperature values are given in degrees Celsius. Resolution +is 1.0 degree. See the datasheet for details. + +The w83l785ts driver will not update its values more frequently than +every other second; reading them more often will do no harm, but will +return 'old' values. + +Known Issues +------------ + +On some systems (Asus), the BIOS is known to interfere with the driver +and cause read errors. Or maybe the W83L785TS-S chip is simply unreliable, +we don't really know. The driver will retry a given number of times +(5 by default) and then give up, returning the old value (or 0 if +there is no old value). It seems to work well enough so that you should +not notice anything. Thanks to James Bolt for helping test this feature. |
