If loading gauge reading is located at one of the hysteresis range and stay
at this range for TIMEOUT_CNT monitoring times, the current section will
return to the previous one.

These bits are for pre-control machine use that is for fan control by loading
status. When loading status increases promptly over the setting as below,
fan control system will pre-control fan speed up to cool down the predict
raising temperature. This value is base on LG_READING [17:6] register.

Default 6.4 seconds (800ms per step). These bits will be used with
Loading Increase Control register. When fan speed increasing to expect
status (follow the LOAD_UP_TIME), user can fill out these two bits register
to decide period of hold time.
Default 4 seconds (400ms per step).
LOAD_RANGE_SEL setting, user can set the raising time of fan speed.
Set this bit to 1 for sorting hysteresis. It will be auto cleared after finish
sorting.
Reserved
Set this bit to enable one-shot. If one-shot is finished, gauge_counter_dis
bit will be set to 1. If another one-shot is needed, just write
gauge_counter_dis bit to 0
