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.
FAN2 full speed count reading (LSB).
VT2 BOUNDARY 1 TEMPERATURE – Offset B6h
Bit
Name
R/W Reset 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 (Offset Bah).
3Ch ^{When VT2 temperature is under this boundary – hysteresis,}
7-0 BOUND1TMP2 R/W 5VSB _{(60oC) FAN2 expect value will load from segment 2 register (Offset}
BAh).
This byte is a 2’s complement value ranging from -128’C ~
127’C.
VT2 BOUNDARY 2 TEMPERATURE – Offset B7
Bit
Name
R/W Reset 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 (Offset BBh).
7-0
BOUND2TMP2

32 When VT2 temperature is below this boundary – hysteresis,
(50ºC) FAN2 expected value will load from segment 3 register (Offset
BCh).
This byte is a 2’s complement value ranging from -128ºC ~
127ºC.
VT2 BOUNDARY 3 TEMPERATURE – Offset 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 (Offset BCh).
7-0
BOUND3TMP2
R/W
5VSB
28h When VT2 temperature is below this boundary – hysteresis,
(40ºC) FAN2 expected value will load from segment 4 register (Offset
BDh).
This byte is a 2’s complement value ranging from -128ºC ~
127ºC.
