User expect fan2 count value, program this register to control the
expect fan2 speed
PWMOUT2 duty cycle. This register is programmable at MANUAL
mode. At SPEED or TEMPERATURE mode, this register reflects
current PWMOUT duty-cycle.
This value determines the gap of current PWMOUT2 duty-cycle and
FAN2_RAISE_DUTY. After current PWMOUT2 duty-cycle is larger
than (FAN2_RAISE_DUTY + F2_NZ_WAIT), it starts to compare if
the current fan count equals to FFFFh, which is one of the condition
of FAN2 Non-zero-PWM fault.
This value determines the tolerance of fan expect count.
When
(1). FAN2 current count > (FAN2_EXPECT + FAN2_EXPTOL),
Increasing PWM duty.
