7.59 Fan 1 PWM Stop Duty Cycle Register ⎯ Index 88h (Bank 0)
Power on default: 01h
BIT
NAME
ATTRIBUTE
DESCRIPTION
7-0 STOP_DC1[7:0]
R/W
In Thermal Cruise mode, PWM duty will be 0 if it
decreases to under this value. This register should be
written a non-zero minimum PWM stop duty cycle.
7.60 Fan 2 PWM Stop Duty Cycle Register ⎯ 89h (Bank 0)
Power on default: 01h
BIT
NAME
7-0 STOP_DC2[7:0]
ATTRIBUTE
R/W
DESCRIPTION
In Thermal Cruise mode, PWM duty will be 0 if it
decreases to under this value. This register should be
written a non-zero minimum PWM stop duty cycle.
7.61 Fan 1 Start-up Duty Cycle Register ⎯ Index 8Ah (Bank 0)
Power on default: 01h
BIT
NAME
ATTRIBUTE
DESCRIPTION
7-0 START_DC1[7:0]
R/W
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.
7.62 Fan 2 Start-up Duty Cycle Register ⎯ Index 8Bh (Bank 0)
Power on default: 01h
BIT
NAME
7-0 START_DC2[7:0]
ATTRIBUTE
R/W
DESCRIPTION
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.
7.63 Fan 1 Stop Time Register ⎯ Index 8Ch (Bank 0)
Power on default: 3Ch
BIT
NAME
ATTRIBUTE
DESCRIPTION
7-0 STOP_TIME1[7:0]
R/W
In Thermal Cruise mode, this register determines the
time of which PWM duty is from stop duty cycle to 0 duty
cycle. The unit of this register is 0.1 second. The default
value is 6 seconds.
