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 is exceeded by 0.25°C. The THERM pin remains asserted until the temperature is equal to or below the
THERM limit. The minimum time that THERM asserts is one monitoring cycle. This allows clock modulation
of devices that incorporate this feature.
THRM = 0 makes the THERM pin act as an input when Pin 9 is configured as THERM , for example, for
Pentium 4 PROCHOT monitoring.
These bits determine the PWM duty cycle vs. the temperature slope for automatic fan control.
