^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  18) Description provided by Dave Pivin @ Andigilog:
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  19) 
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  20) Andigilog has both the PECI and pre-PECI versions of the Heceta-6, as
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  21) Intel calls them. Heceta-6e has high frequency PWM and Heceta-6p has
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  22) added PECI and a 4th thermal zone. The Andigilog aSC7611 is the
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  23) Heceta-6e part and aSC7621 is the Heceta-6p part. They are both in
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  24) volume production, shipping to Intel and their subs.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  25) 
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  26) We have enhanced both parts relative to the governing Intel
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  27) specification. First enhancement is temperature reading resolution. We
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  28) have used registers below 20h for vendor-specific functions in addition
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  29) to those in the Intel-specified vendor range.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  30) 
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  31) Our conversion process produces a result that is reported as two bytes.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  32) The fan speed control uses this finer value to produce a "step-less" fan
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  33) PWM output. These two bytes are "read-locked" to guarantee that once a
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  34) high or low byte is read, the other byte is locked-in until after the
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  35) next read of any register. So to get an atomic reading, read high or low
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  36) byte, then the very next read should be the opposite byte. Our data
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  37) sheet says 10-bits of resolution, although you may find the lower bits
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  38) are active, they are not necessarily reliable or useful externally. We
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  39) chose not to mask them.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  40) 
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  41) We employ significant filtering that is user tunable as described in the
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  42) data sheet. Our temperature reports and fan PWM outputs are very smooth
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  43) when compared to the competition, in addition to the higher resolution
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  44) temperature reports. The smoother PWM output does not require user
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  45) intervention.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  46) 
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  47) We offer GPIO features on the former VID pins. These are open-drain
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  48) outputs or inputs and may be used as general purpose I/O or as alarm
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  49) outputs that are based on temperature limits. These are in 19h and 1Ah.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  50) 
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  51) We offer flexible mapping of temperature readings to thermal zones. Any
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  52) temperature may be mapped to any zone, which has a default assignment
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  53) that follows Intel's specs.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  54) 
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  55) Since there is a fan to zone assignment that allows for the "hotter" of
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  56) a set of zones to control the PWM of an individual fan, but there is no
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  57) indication to the user, we have added an indicator that shows which zone
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  58) is currently controlling the PWM for a given fan. This is in register
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  59) 00h.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  60) 
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  61) Both remote diode temperature readings may be given an offset value such
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  62) that the reported reading as well as the temperature used to determine
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  63) PWM may be offset for system calibration purposes.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  64) 
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  65) PECI Extended configuration allows for having more than two domains per
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  66) PECI address and also provides an enabling function for each PECI
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  67) address. One could use our flexible zone assignment to have a zone
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  68) assigned to up to 4 PECI addresses. This is not possible in the default
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  69) Intel configuration. This would be useful in multi-CPU systems with
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  70) individual fans on each that would benefit from individual fan control.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  71) This is in register 0Eh.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  72) 
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  73) The tachometer measurement system is flexible and able to adapt to many
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  74) fan types. We can also support pulse-stretched PWM so that 3-wire fans
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  75) may be used. These characteristics are in registers 04h to 07h.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  76) 
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  77) Finally, we have added a tach disable function that turns off the tach
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  78) measurement system for individual tachs in order to save power. That is
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  79) in register 75h.

^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  83) aSC7621 Product Description
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  84) ===========================
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  85) 
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  86) The aSC7621 has a two wire digital interface compatible with SMBus 2.0.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  87) Using a 10-bit ADC, the aSC7621 measures the temperature of two remote diode
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  88) connected transistors as well as its own die. Support for Platform
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  89) Environmental Control Interface (PECI) is included.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  90) 
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  91) Using temperature information from these four zones, an automatic fan speed
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  92) control algorithm is employed to minimize acoustic impact while achieving
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  93) recommended CPU temperature under varying operational loads.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  94) 
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  95) To set fan speed, the aSC7621 has three independent pulse width modulation
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  96) (PWM) outputs that are controlled by one, or a combination of three,
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  97) temperature zones. Both high- and low-frequency PWM ranges are supported.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  98) 
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  99) The aSC7621 also includes a digital filter that can be invoked to smooth
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 100) temperature readings for better control of fan speed and minimum acoustic
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 101) impact.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 102) 
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 103) The aSC7621 has tachometer inputs to measure fan speed on up to four fans.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 104) Limit and status registers for all measured values are included to alert
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 105) the system host that any measurements are outside of programmed limits
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 106) via status registers.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 107) 
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 108) System voltages of VCCP, 2.5V, 3.3V, 5.0V, and 12V motherboard power are
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 109) monitored efficiently with internal scaling resistors.
