aSC7512
Figure 9 Automatic Fan Control Algorithm
Fan Register Device Set-Up
The BIOS will follow the following steps to configure the fan registers on the aSC7512. The registers corresponding to each
function are listed. All steps may not be necessary if default values are acceptable. Regardless of all changes made by the
BIOS to the fan limit and parameter registers during configuration, the aSC7512 will continue to operate based on default
values until the START bit (bit 0), in the Ready/Lock/Start/Override register (address 40h), is set. Once the fan mode is
updated, by setting the START bit to 1, the aSC7512 will operate using the values that were set by the BIOS in the fan
control limit and parameter registers (address in the range 5Ch through 6Dh).
1. Set limits and parameters (not necessarily in this order):
[5F-60h] Set PWM frequency for the fan and auto fan control range for each zone.
[62-63h] Set spike smoothing and min/off.
[5Ch] Set the fan spin-up delay.
[75h] Set PWM spin-up mode to terminate after time set in [5Ch]. Value = 00h instead of default 01h.
[5Ch] Match fan with a corresponding thermal zone.
[67-68h] Set the fan temperature limits.
[6A-6Bh] Set the temperature absolute limits.
[64h] Set the PWM minimum duty cycle.
[6Dh] Set the temperature hysteresis values.
2. [40h] Set bit 0 (START) to update fan control and limit register values and start fan control based on these new
values.
[40h] (Optional) Set bit 1 (LOCK) to lock the fan limit and parameter registers.
WARNING:
this is a
non-reversible
change in state and locks out further change in critical fan control parameters until power is removed from the aSC7512.
