Depend on the FAN1_MODE(CR96[1:0]) register setting:
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.
Depend on the FAN1_MODE(CR96[1:0]) register setting:
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.
Depend on the FAN1_MODE(CR96[1:0]) register setting:
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.
If this bit set to 1, when detect loading increase acutely, fan1 will pre-up
fan speed
If this bit set to 1, fan1 min duty will in duty that define in CR9C
Set 1 to force FAN1 to the highest speed if any temperature over its high
limit.
Set 1 will enable the interpolation of the fan expect table.
(Auto Linear Mode)
Set 1 that FAN1 speed will jump to FAN1 SEGMENT 1 SPEED when
temperature over T1 Boundary 1.
Set 0 that FAN1 speed will raise up to FAN1 SEGMENT 1 SPEED by slop
value( CR9B) when temperature over T1 Boundary 1.
Set 1 that FAN1 speed will jump to FAN1 SEGMENT 2 SPEED when
temperature under FAN1 Boundary Hystersis.
Set 0 that FAN1 speed will decrease to FAN1 SEGMENT 2 SPEED by
slop value( CR9B) when temperature under FAN1 Boundary Hystersis.
0: fan1 follow local temperature.
1: fan1 follow temperature 1.
2: fan1 follow temperature 2.
3: fan1 follow temperature 3.
