VT2 BOUNDARY 3 TEMPERATURE – Index B8h
Bit
Name
R/W Reset Default
Description
The 3rd BOUNDARY temperature for VT2 in temperature mode.
When VT2 temperature is exceed this boundary, FAN2 expected value
28h will load from segment 3 register (index BCh).
7-0
BOUND3TMP2
R/W 5VSB _{(40ºC) When VT2 temperature is below this boundary – hysteresis, FAN2}
expected value will load from segment 4 register (index BDh).
This byte is a 2’s complement value ranging from -128^ºC ~ 127^ºC.
VT2 BOUNDARY 4 TEMPERATURE – Index B9
Bit
Name
R/W Reset Default
Description
The 4th BOUNDARY temperature for VT2 in temperature mode.
When VT2 temperature is exceed this boundary, FAN2 expected value
1Eh will load from segment 4 register (index BDh).
7-0
BOUND4TMP2
R/W 5VSB _{(30ºC) When VT2 temperature is below this boundary – hysteresis, FAN2}
expected value will load from segment 5 register (index BEh).
This byte is a 2’s complement value ranging from -128^ºC ~ 127^ºC.
FAN2 SEGMENT 1 SPEED COUNT – Index BAh
Bit
Name
R/W Reset Default
Description
The meaning of this register is depending on the FAN2_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.
7-0
SEC1SPEED2
Ex:
FFh
R/W 5VSB
100%:full speed: User must set this register to 0.
(100%)
60% full speed: (100-60)*32/60, so user must program 21 to this reg.
X% full speed: The value programming in this byte is Î (100-X)*32/X
2’b01: The value that set in this byte is mean the expect PWM
duty-cycle in this temperature section.
FAN2 SEGMENT 2 SPEED COUNT – Index BBh
Bit
Name
R/W Reset Default
Description
The meaning of this register is depending on the FAN2_MODE (CR96)
2’b00: The value that set in this byte is the relative expect fan speed %
D9h
7-0
SEC2SPEED2
R/W 5VSB
of the full speed in this temperature section.
(85%)
2’b01: The value that set in this byte is mean the expect PWM
duty-cycle in this temperature section.
