VT1 BOUNDARY 2 TEMPERATURE – Offset A7
Bit
Name
R/W Reset Default
Description
The 2nd BOUNDARY temperature for VT1 in temperature mode.
When VT1 temperature is exceed this boundary, FAN1 expected
value will load from segment 2 register (Offset ABh).
7-0
BOUND2TMP1
R/W
5VSB
32 When VT1 temperature is below this boundary – hysteresis,
(50ºC) FAN1 expected value will load from segment 3 register (Offset
ACh).
This byte is a 2’s complement value ranging from -128ºC ~
127ºC.
VT1 BOUNDARY 3 TEMPERATURE – Offset A8h
Bit
Name
R/W Reset Default
Description
The 3rd BOUNDARY temperature for VT1 in temperature mode.
When VT1 temperature is exceed this boundary, FAN1 expected
value will load from segment 3 register (Offset ACh).
7-0
BOUND3TMP1
R/W
5VSB
28h When VT1 temperature is below this boundary – hysteresis,
(40ºC) FAN1 expected value will load from segment 4 register (Offset
ADh).
This byte is a 2’s complement value ranging from -128ºC ~
127ºC.
VT1 BOUNDARY 4 TEMPERATURE – Offset A9
Bit
Name
R/W Reset Default
Description
The 4th BOUNDARY temperature for VT1 in temperature mode.
When VT1 temperature is exceed this boundary, FAN1 expected
value will load from segment 4 register (Offset ADh).
7-0
BOUND4TMP1
R/W
5VSB
1Eh When VT1 temperature is below this boundary – hysteresis,
(30ºC) FAN1 expected value will load from segment 5 register (Offset
AEh).
This byte is a 2’s complement value ranging from -128ºC ~
127ºC.
FAN1 SEGMENT 1 SPEED COUNT – Offset AAh
Bit
Name
R/W Reset Default
Description
The meaning of this register is depending on the
FAN1_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 SEC1SPEED1
R/W 5VSB ^{FFh 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
( (100-X)*32/X
2’b01: The value that set in this byte is mean the expect PWM
duty-cycle in this temperature section.
