7.37 Fan 2 PWM Stop Duty Cycle Register -- 89h (Bank 0)
Power on default [7:0] = 0000, 0001 b
BIT
NAME
7-0 STOP_DC2[7:0]
READ/WRITE
Read/Write
DESCRIPTION
In Thermal Cruise mode, PWM duty will be 0 if it
decreases to under this register value. This register
should be written a non-zero minimum PWM stop duty
cycle.
7.38 Fan 1 Start-up Duty Cycle Register -- Index 8Ah
Power on default [7:0] = 0000, 0001 b
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.
7.39 Fan 2 Start-up Duty Cycle Register -- Index 8Bh
Power on default [7:0] = 0000, 0001 b
BIT
NAME
READ/WRITE
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.
7.40 Fan 1 Stop Time Register -- Index 8Ch
Power on default [7:0] = 0011, 1100 b
BIT
NAME
READ/WRITE
DESCRIPTION
7-0 STOP_TIME1[7:0] Read/Write
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.
7.41 Fan 2 Stop Time Register -- Index 8Dh
Power on default [7:0] = 0011, 1100 b
BIT
NAME
READ/WRITE
DESCRIPTION
7-0 STOP_TIME2[7:0] Read/Write
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.
