VT3 BOUNDARY 3 TEMPERATURE – Offset 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 will load from segment 3 register (Offset CCh).
7-0
BOUND3TMP3
R/W
5VSB
28h When VT3 temperature is below this boundary – hysteresis,
(40^oC) FAN3 expected value will load from segment 4 register (Offset
CDh).
This byte is a 2’s complement value ranging from -128 ^oC ~ 127
o_C.
VT3 BOUNDARY 4 TEMPERATURE – Offset 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 will load from segment 4 register (Offset CDh).
7-0
BOUND4TMP3
R/W
5VSB
1Eh When VT3 temperature is below this boundary – hysteresis,
(30^oC) FAN3 expected value will load from segment 5 register (Offset
CEh).
This byte is a 2’s complement value ranging from -128 ^oC ~ 127
o_C.
FAN3 SEGMENT 1 SPEED COUNT – Offset 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.
Ex:
7-0 SEC1SPEED3
FFh ^{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.
