These bits control the PWMx frequency (only apply when PWM channel is in low frequency
mode).
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
HF/LF = 1, High frequency PWM mode is enabled for PWMx.
HF/LF = 0, Low frequency PWM mode is enabled for PWMx.
These bits determine the PWM duty cycle vs. the temperature range for automatic fan
control.
