Table 59. Register 0x7B—TACH Pulses per Revolution Register (Power-On Default = 0x55)
Bit
Name
R/W
Description
[1:0]
FAN1
R/W
Sets number of pulses to be counted when measuring Fan 1 speed. Can be used to determine fan
pulses per revolution for unknown fan type.
Pulses Counted:
00 = 1
01 = 2 (default)
10 = 3
11 = 4
[3:2]
FAN2
R/W
Sets number of pulses to be counted when measuring Fan 2 speed. Can be used to determine fan
pulses per revolution for unknown fan type.
Pulses Counted:
00 = 1
01 = 2 (default)
10 = 3
11 = 4
[5:4]
FAN3
R/W
Sets number of pulses to be counted when measuring Fan 3 speed. Can be used to determine fan
pulses per revolution for unknown fan type.
Pulses Counted:
00 = 1
01 = 2 (default)
10 = 3
11 = 4
[7:6]
FAN4
R/W
Sets number of pulses to be counted when measuring Fan 4 speed. Can be used to determine fan
pulses per revolution for unknown fan type.
Pulses Counted:
00 = 1
01 = 2 (default)
10 = 3
11 = 4
Table 60. Register 0x7C—Configuration Register 5 (ADT7473 Power-On Default = 0x00)
Bit
Name
R/W1
Description
[0]
TWOS
COMPL
R/W
Twos complement = 1, sets the temperature range to twos complement temperature range.
Twos complement = 0, changes the temperature range to Offset 64. When this bit is changed, the
ADT7473/ADT7473-1 interprets all relevant temperature register values as defined by this bit.
[1]
TempOffset
TempOffset = 0 sets offset range to ±64°C at 0.5°C resolution.
TempOffset = 1 sets offset range to ±128°C at 1°C resolution.
[2]
GPIOD
GPIO direction. When GPIO function is enabled, this determines whether the GPIO is an input (0) or an
output (1).
[3]
GPIOP
GPIO polarity. When the GPIO function is enabled and is programmed as an output, this bit
determines whether the GPIO is active low (0) or high (1).
[4]
RES
THERM
Hysteresis
Reserved on the ADT7473
On the ADT7473-1:
0 = THERM hysteresis disabled
1 = THERM hysteresis enabled
[5]
R1 THERM
R/W
R1 THERM = 1, THERM temperature limit functionality enabled for Remote 1 temperature channel;
that is, THERM is bidirectional. R1 THERM = 0, THERM is a timer input only.
THERM can also be disabled on any channel by
Writing 64C to the appropriate THERM temperature limit in Offset 64 mode.
Writing 128C to the appropriate THERM temperature limit in twos complement mode.
