20 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

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

87 Using a 10-bit ADC, the aSC7621 measures the temperature of two remote diode
96 (PWM) outputs that are controlled by one, or a combination of three,
97 temperature zones. Both high- and low-frequency PWM ranges are supported.
