Description

Round Robin
R/W
This bit enables the round-robin mode. Set this bit to 0 to put the ADM1033 in
single-channel mode. The ADC converts on one channel only, which is determined
by the channel selector bits. Default = Round Robin = 1.

Channel Selector
R/W
This bit determines the channel on which the ADC converts.
00 = Local Channel Only
01 = Remote 1 Channel Only
10 = Reserved
11 = Reserved

2
Discrete/Linear Speed
R/W
This bit determines whether the fans run at discrete speeds or at speeds that
increase with temperature between the two thresholds. Default = 1 = Linear.
1
Boost Disable
R/W
Set bit to 1 to prevent the fans from being boosted if either THERM
temperature or
THERM
timer limits are exceeded. Under these conditions, the fan runs at the
previously calculated speed. Default = 0.
0
SW Reset
R/W
Set this bit to 1 to reset the ADM1033 registers to their default values, excluding the
limit registers, offset registers, and Look-up table registers. This bit self-clears.
Default = 0.

#Poles Fan
R/W
Write the number of poles in Fan to this register. power-on default = 4 poles = 100.
This should always be an even number, because there cannot be an odd number of
poles in a fan.

R/W
This bit sets the function for Pin 8. 0 = Default = FAN_FAULT
output (THERM
input
is CMOS). 1 = Reference input for THERM
.

THERM
% Time Window
R/W
These bits set the time window over which THERM
% is calculated.
000 = 0.25 second
001 = 0.5 second
010 = 1 second
011 = 2 seconds
100 = 4 seconds
101 = 8 seconds
110 = 8 seconds
111 = 8 seconds

XOR Test
R/W
Set this bit to 1 to enable the XOR connectivity test.

1
Enable Remote 1 THERM
Events
R/W
This bit enables THERM
assertions as an output. Functions when the THERM
timer
is enabled and the Remote 1 temperature exceeeds its THERM
limit.
0
Enable Local THERM
Events
R/W
This bit enables THERM
assertions as an output. Functions when the THERM
timer
is enabled and the local temperature exceeeds its THERM
limit.
