-Description provided by Dave Pivin @ Andigilog:
-
-Andigilog has both the PECI and pre-PECI versions of the Heceta-6, as
-Intel calls them. Heceta-6e has high frequency PWM and Heceta-6p has
-added PECI and a 4th thermal zone. The Andigilog aSC7611 is the
-Heceta-6e part and aSC7621 is the Heceta-6p part. They are both in
-volume production, shipping to Intel and their subs.
-
-We have enhanced both parts relative to the governing Intel
-specification. First enhancement is temperature reading resolution. We
-have used registers below 20h for vendor-specific functions in addition
-to those in the Intel-specified vendor range.
-
-Our conversion process produces a result that is reported as two bytes.
-The fan speed control uses this finer value to produce a "step-less" fan
-PWM output. These two bytes are "read-locked" to guarantee that once a
-high or low byte is read, the other byte is locked-in until after the
-next read of any register. So to get an atomic reading, read high or low
-byte, then the very next read should be the opposite byte. Our data
-sheet says 10-bits of resolution, although you may find the lower bits
-are active, they are not necessarily reliable or useful externally. We
-chose not to mask them.
-
-We employ significant filtering that is user tunable as described in the
-data sheet. Our temperature reports and fan PWM outputs are very smooth
-when compared to the competition, in addition to the higher resolution
-temperature reports. The smoother PWM output does not require user
-intervention.
-
-We offer GPIO features on the former VID pins. These are open-drain
-outputs or inputs and may be used as general purpose I/O or as alarm
-outputs that are based on temperature limits. These are in 19h and 1Ah.
-
-We offer flexible mapping of temperature readings to thermal zones. Any
-temperature may be mapped to any zone, which has a default assignment
-that follows Intel's specs.
-
-Since there is a fan to zone assignment that allows for the "hotter" of
-a set of zones to control the PWM of an individual fan, but there is no
-indication to the user, we have added an indicator that shows which zone
-is currently controlling the PWM for a given fan. This is in register
-00h.
-
-Both remote diode temperature readings may be given an offset value such
-that the reported reading as well as the temperature used to determine
-PWM may be offset for system calibration purposes.
-
-PECI Extended configuration allows for having more than two domains per
-PECI address and also provides an enabling function for each PECI
-address. One could use our flexible zone assignment to have a zone
-assigned to up to 4 PECI addresses. This is not possible in the default
-Intel configuration. This would be useful in multi-CPU systems with
-individual fans on each that would benefit from individual fan control.
-This is in register 0Eh.
-
-The tachometer measurement system is flexible and able to adapt to many
-fan types. We can also support pulse-stretched PWM so that 3-wire fans
-may be used. These characteristics are in registers 04h to 07h.
-
-Finally, we have added a tach disable function that turns off the tach
-measurement system for individual tachs in order to save power. That is
-in register 75h.

-aSC7621 Product Description
-===========================
-
-The aSC7621 has a two wire digital interface compatible with SMBus 2.0.
-Using a 10-bit ADC, the aSC7621 measures the temperature of two remote diode
-connected transistors as well as its own die. Support for Platform
-Environmental Control Interface (PECI) is included.
-
-Using temperature information from these four zones, an automatic fan speed
-control algorithm is employed to minimize acoustic impact while achieving
-recommended CPU temperature under varying operational loads.
-
-To set fan speed, the aSC7621 has three independent pulse width modulation
-(PWM) outputs that are controlled by one, or a combination of three,
-temperature zones. Both high- and low-frequency PWM ranges are supported.
-
-The aSC7621 also includes a digital filter that can be invoked to smooth
-temperature readings for better control of fan speed and minimum acoustic
-impact.
-
-The aSC7621 has tachometer inputs to measure fan speed on up to four fans.
-Limit and status registers for all measured values are included to alert
-the system host that any measurements are outside of programmed limits
-via status registers.
-
-System voltages of VCCP, 2.5V, 3.3V, 5.0V, and 12V motherboard power are
-monitored efficiently with internal scaling resistors.
