FAN2 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.

Name
R/W Default
Description
The first boundary temperature for VT2 in temperature mode.
When VT2 temperature exceeds this boundary, FAN2 expect value
will load from segment 1 register (index Bah).

BOUND1TMP2 R/W
(60oC)
When VT2 temperature is under this boundary – hysteresis, FAN2
expect value will load from segment 2 register (index BAh).
This byte is a 2’s complement value ranging from -128’C ~ 127’C.
6.6.78 VT2 BOUNDARY 2 TEMPERATURE – Index B7
Bit
Name
R/W Default
Description
The 2nd BOUNDARY temperature for VT2 in temperature mode.
When VT2 temperature is exceed this boundary, FAN2 expected
value will load from segment 2 register (index BBh).
When VT2 temperature is below this boundary – hysteresis, FAN2
expected value will load from segment 3 register (index BCh).
This byte is a 2’s complement value ranging from -128ºC ~ 127ºC.
