VT2 BOUNDARY 4 TEMPERATURE – Offset 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 will load from segment 4 register (Offset BDh).
7-0
BOUND4TMP2
R/W
5VSB
1Eh When VT2 temperature is below this boundary – hysteresis,
(30ºC) FAN2 expected value will load from segment 5 register (Offset
BEh).
This byte is a 2’s complement value ranging from -128ºC ~
127ºC.
FAN2 SEGMENT 1 SPEED COUNT – Offset 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.
Ex:
7-0 SEC1SPEED2
R/W
FFh ^{100%:full speed: User must set this register to 0.}
5VSB _{(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 – Offset BBh
Bit
Name
R/W Reset Default
Description

FAN2_MODE(CR96)
D9h ^{2’b00: The value that set in this byte is the relative expect fan}

SEC2SPEED2
R/W 5VSB _{(85%) 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.
