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.
2’b01: The value that set in this byte is mean the expect PWM duty-cycle
in this temperature section.

Set 1 that FAN speed will jump to SEC1SPEED when temperature over
BOUND1TEMP CRD9.
Set 0 that FAN1 speed will raise up to SEC1SPEED by slop value (CR9A)
when temperature over BOUND1TEMP CRD9..
Set 1 that FAN speed will jump to SEC2SPEED when temperature under
BOUND1TEMP Hystersis.
Set 0 that FAN speed will decrease to SEC2SPEED by slop value (CR9B)
when temperature under FAN1 Boundary Hystersis.
