VT1 BOUNDARY 3 TEMPERATURE – Index 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 (index ACh).
When VT1 temperature is below this boundary – hysteresis, FAN1
expected value will load from segment 4 register (index ADh).
This byte is a 2’s complement value ranging from -128ºC ~ 127ºC.

VT1 BOUNDARY 4 TEMPERATURE – Index 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 (index ADh).
When VT1 temperature is below this boundary – hysteresis, FAN1
expected value will load from segment 5 register (index AEh).
This byte is a 2’s complement value ranging from -128ºC ~ 127ºC.

FAN1 SEGMENT 1 SPEED COUNT – Index 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:

R/W
100%:full speed: User must set this register to 0.
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.
