Bit
Name
Read/Write
Description
7-0 START_DC1[7:0]
Read/Write
In Thermal Cruise mode, PWM duty will increase from 0
to this register value to provide a minimum duty cycle to
turn on the fan. This register should be written a fan start-
up duty cycle.

Description
7-0 START_DC2[7:0]
Read/Write
In Thermal Cruise mode, PWM duty will increase from 0
to this register value to provide a minimum duty cycle to
turn on the fan. This register should be written a fan start-
up duty cycle.
