If bit 6 in FAN_CONFIG_1_2 is set to zero, the FAN SPEED STEP sets the fan PWM duty cycle at each temperature step
breakpoint. The valid duty cycle range is 0 to 100 (inclusive). Any values greater than 100 (decimal) result in 100% PWM
duty cycle being generated, and any values less than 0 (decimal) result in 0% PWM duty cycle.
If bit 6 in FAN_CONFIG_1_2 is set to 1, the FAN SPEED STEP sets the fan target speed (in RPM) at each temperature
step breakpoint. The valid fan speed range is 0 to 32,767 (inclusive).
