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
will load from segment 3 register (index CCh).
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-128ºC ~ 127ºC.

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: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.
