FAN3 expect speed count value (LSB) or expect PWM duty , in auto fan mode
this register is auto updated by hardware and read only.
Duty mode(CR96 bit4=1):
The Value programming in this byte is duty value. In auto fan mode(CR96
bit5
Ex:
FAN3 full speed count reading (MSB). At the moment of reading this register,
the LSB will be latched. This will prevent from data updating when reading. To
read the fan count correctly, read MSB first and followed read the LSB.

The 1
When VT3 temperature is exceed this boundary, FAN3 expect value will
load from segment 1 register (index CA)h.
When VT3 temperature is below this boundary – hysteresis, FAN3 expect
value will load from segment 2 register (index CAh).
Return 0 when read.
The 2
When VT3 temperature is exceed this boundary, FAN3 expect value will
load from segment 2 register (index CB)h.
When VT3 temperature is below this boundary – hysteresis, FAN3 expect
value will load from segment 3 register (index CBh).
Return 0 when read.
The 3
When VT3 temperature is exceed this boundary, FAN3 expect value will
load from segment 3 register (index CC)h.
When VT3 temperature is below this boundary – hysteresis, FAN3 expect
value will load from segment 4 register (index CCh).
Return 0 when read.
The 4
When VT3 temperature is exceed this boundary, FAN3 expect value will
load from segment 4 register (index CDh).
When VT3 temperature is below this boundary – hysteresis, FAN3 expect
value will load from segment 5 register (index CDh).
