The meaning of this register is depending on the FAN_MODE(CR96)
2’b00: The value that set in this byte is the relative expect fan speed % of
the full speed in this temperature section.
Ex:
100%:full speed: User must set this register to 0.
2’b01: The value that set in this byte is mean the expect PWM duty-cycle
in this temperature section.
