H A Dasc7621.rst20 Andigilog has both the PECI and pre-PECI versions of the Heceta-6, as
21 Intel calls them. Heceta-6e has high frequency PWM and Heceta-6p has
23 Heceta-6e part and aSC7621 is the Heceta-6p part. They are both in
27 specification. First enhancement is temperature reading resolution. We
28 have used registers below 20h for vendor-specific functions in addition
29 to those in the Intel-specified vendor range.
32 The fan speed control uses this finer value to produce a "step-less" fan
33 PWM output. These two bytes are "read-locked" to guarantee that once a
34 high or low byte is read, the other byte is locked-in until after the
