Description
These bits control the PWMx frequency.
000 = 11.0 Hz
001 = 14.7 Hz
010 = 22.1 Hz
011 = 29.4 Hz
100 = 35.3 Hz (default)
101 = 44.1 Hz
110 = 58.8 Hz
111 = 88.2 Hz
THRM = 1 causes the
THERM
pin (Pin 9) to assert low as an output when this
temperature channel’s
THERM
limit has been exceeded by 0.25 C. The
THERM
pin
will remain asserted until the temperature is equal to or below the
THERM
limit. The
minimum time that
THERM
asserts for is one monitoring cycle. This allows clock
modulation of devices that incorporate this feature.
THRM = 0 makes the
THERM
pin act as an input only, e.g., for Pentium 4
PROCHOT
monitoring, when Pin 9 is configured as
THERM
.
These bits determine the PWM Duty Cycle versus Temperature Slope for
Automatic Fan Control.
0000 = 2 C
0001 = 2.5 C
0010 = 3.33 C
0011 = 4 C

0110 = 8 C
0111 = 10 C
1000 = 13.33 C
1001 = 16 C
1010 = 20 C
1011 = 26.67 C
1100 = 32 C (default)
1101 = 40 C
1110 = 53.33 C
