Fan X Spin-Up Time.
000 = 200 ms
001 = 400 ms
010 = 600 ms
011 = 800 ms
100 = 1 sec
101 = 2 sec (Default)

T MAX =40 5 C (As seen on Slope 1 of Figure 26)
In this case, since the Minimum Duty Cycle is the default
33%, the equation for T MAX reduces to:
T MAX + T MIN ) ((Max DC * Min DC) T RANGE 10)
T MAX + T MIN ) ((15 * 5) T RANGE 10)

PWM Frequency Driving the Fan.
000 = 11.7 Hz
001 = 15.6 Hz
010 = 23.4 Hz
011 = 31.25 Hz (Default)
100 = 37.5 Hz
101 = 46.9 Hz
110 = 62.5 Hz
111 = 93.5 Hz
Speed Range N; defines the lowest fan speed
that can be measured by the device.
00 = 1: Lowest Speed = 2647 RPM
01 = 2: Lowest Speed = 1324 RPM
10 = 4: Lowest Speed = 662 RPM
11 = 8: Lowest Speed = 331 RPM

Min Speed: This nibble contains the speed at
which the fan runs when the temperature is at
T MIN . The default is 0 ? 05, meaning that the
fan runs at 33% duty cycle when the
temperature is at T MIN .
Min Speed: Determines the minimum PWM
cycle for Fan 2 in automatic fan speed
control mode.
