This register controls the FAN2 duty movement when temperature over
highest boundary.
0: The FAN2 duty will increases with the slope selected by
FAN2_RATE_SEL register (Index 9Bh).
1: The FAN2 duty will directly jumps to full speed.
This register controls the FAN2 duty movement when temperature under
(highest boundary – hysteresis).
0: The FAN2 duty will decreases with the slope selected by
FAN2_RATE_SEL register (Index 9Bh).
1: The FAN2 duty will directly jumps to the value of SEC1SPEED2
register.

FAN3 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.
