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.

6.6.88 VT3 BOUNDARY 1 TEMPERATURE – Index C6h
Bit
Name
R/W Default
Description
The first boundary temperature for VT3 in temperature mode.
When VT3 temperature exceeds this boundary, FAN3 expect value
will load from segment 1 register (index CA)h.

BOUND1TMP3 R/W
(60oC)
When VT3 temperature is under this boundary – hysteresis, FAN3
expect value will load from segment 2 register (index CAh).
This byte is a 2’s complement value ranging from -128’C ~ 127’C.
6.6.89 VT3 BOUNDARY 2 TEMPERATURE – Index C7
Bit
Name
R/W Default
Description
The 2nd BOUNDARY temperature for VT3 in temperature mode.
When VT3 temperature is exceed this boundary, FAN3 expected
value will load from segment 2 register (index CBh).
When VT3 temperature is below this boundary – hysteresis, FAN3
expected value will load from segment 3 register (index CCh).
This byte is a 2’s complement value ranging from -128 oC ~ 127 oC.
