Description
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.
0000 = 2°C
0001 = 2.5°C
0010 = 3.33°C
0011 = 4°C
0100 = 5°C
0101 = 6.67°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
1111 = 80°C
