VT2 BOUNDARY 3 TEMPERATURE – Index B8h
Bit
Name
R/W Reset Default
Description
The 3rd BOUNDARY temperature for VT2 in temperature mode.
When VT2 temperature is exceed this boundary, FAN2 expected value
will load from segment 3 register (index BCh).
When VT2 temperature is below this boundary – hysteresis, FAN2
expected value will load from segment 4 register (index BDh).
This byte is a 2’s complement value ranging from -128ºC ~ 127ºC.

Description
The 4th BOUNDARY temperature for VT2 in temperature mode.
When VT2 temperature is exceed this boundary, FAN2 expected value
will load from segment 4 register (index BDh).
When VT2 temperature is below this boundary – hysteresis, FAN2
expected value will load from segment 5 register (index BEh).
This byte is a 2’s complement value ranging from -128ºC ~ 127ºC.

Description
The meaning of this register is depending on the FAN2_MODE (CR96)

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 Î (100-X)*32/X
2’b01: The value that set in this byte is mean the expect PWM
duty-cycle in this temperature section.
