VT3 BOUNDARY 3 TEMPERATURE – Index C8h
Bit
Name
R/W Reset Default
Description
The 3rd BOUNDARY temperature for VT3 in temperature mode.
When VT3 temperature is exceed this boundary, FAN3 expected value
28h will load from segment 3 register (index CCh).
7-0
BOUND3TMP3
R/W 5VSB _{(40oC) When VT3 temperature is below this boundary – hysteresis, FAN3}
expected value will load from segment 4 register (index CDh).
This byte is a 2’s complement value ranging from-128^ºC ~ 127^ºC.
VT3 BOUNDARY 4 TEMPERATURE – Index C9h
Bit
Name
R/W Reset Default
Description
The 4th BOUNDARY temperature for VT3 in temperature mode.
When VT3 temperature is exceed this boundary, FAN3 expected value
1Eh will load from segment 4 register (index CDh).
7-0
BOUND4TMP3
R/W 5VSB _{(30oC) When VT3 temperature is below this boundary – hysteresis, FAN3}
expected value will load from segment 5 register (index CEh).
This byte is a 2’s complement value ranging from-128^ºC ~ 127^ºC.
FAN3 SEGMENT 1 SPEED COUNT – Index CAh
Bit
Name
R/W Reset Default
Description
The meaning of this register is depending on the FAN3_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
SEC1SPEED3
FFh ^{Ex:100%:full speed: User must set this register to 0.}
R/W 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 ( (100-X)*32/X
2’b01: The value that set in this byte is mean the expect PWM duty-cycle
in this temperature section.
FAN3 SEGMENT 2 SPEED COUNT – Index CBh
Bit
Name
R/W Reset Default
Description
The meaning of this register is depending on the FAN3_MODE (CR96)
2’b00: The value that set in this byte is the relative expect fan speed % of
D9h
7-0 SEC2SPEED3 R/W 5VSB
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.
