Fan Spin Up Configuration Register
The Fan Spin Up Configuration Register controls the settings of Spin Up Routine.
Bit 7 - 6 - DRIVE_FAIL_CNT[1:0] - Determines how many update cycles are used for the Drive Fail
detection function as shown in Table 6.40. This circuitry determines whether the fan can be driven to
the desired tach target.
Bit 5 - NOKICK - Determines if the Spin Up Routine will drive the fan to 100% duty cycle for 1/4 of the
programmed spin up time before driving it at the programmed level.
‘0’ (default) - The Spin Up Routine will drive the PWM to 100% for 1/4 of the programmed spin up
time before reverting to the programmed spin level.
‘1’ - The Spin Up Routine will not drive the PWM to 100%. It will set the drive at the programmed
spin level for the entire duration of the programmed spin up time.
