W83697HF/ HG
Fan 1 Start-up Duty Cycle Register -- Index 0Ah
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.
Fan 2 Start-up Duty Cycle Register -- Index 0Bh
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.
Fan 1 Stop Time Register -- Index 0Ch
Power on default [7:0] = 0011,1100 b
BIT
NAME
READ/WRITE
7-0 STOP_TIME1[7:0] Read/Write
DESCRIPTION
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.
Fan 2 Stop Time Register -- Index 0Dh
Power on default [7:0] = 0011,1100 b
BIT
NAME
READ/WRITE
7-0 STOP_TIME2[7:0] Read/Write
DESCRIPTION
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.
