Table 75. REGISTER 0X73 CONFIGURATION REGISTER 2 (POWERON DEFAULT = 0X00) (Note 1)
Bit
Name
R/W
Description
0
AIN1
R/W
AIN1 = 0, Speed of 3wire fans measured using the TACH output from the fan.
AIN1 = 1, Pin 11 is reconfigured to measure the speed of 2wire fans using an external sensing
resistor and coupling capacitor. AIN voltage threshold is set via Configuration Register 4
(Reg. 0x7D).
1
AIN2
R/W
AIN2 = 0, Speed of 3wire fans measured using the TACH output from the fan.
AIN2 = 1, Pin 12 is reconfigured to measure the speed of 2wire fans using an external sensing
resistor and coupling capacitor. AIN voltage threshold is set via Configuration Register 4
(Reg. 0x7D).
2
AIN3
R/W
AIN3 = 0, Speed of 3wire fans measured using the TACH output from the fan.
AIN3 = 1, Pin 9 is reconfigured to measure the speed of 2wire fans using an external sensing
resistor and coupling capacitor. AIN voltage threshold is set via Configuration Register 4
(Reg. 0x7D).
3
AIN4
R/W
AIN4 = 0, Speed of 3wire fans measured using the TACH output from the fan.
AIN4 = 1, Pin 14 is reconfigured to measure the speed of 2wire fans using an external sensing
resistor and coupling capacitor. AIN voltage threshold is set via Configuration Register 4
(Reg. 0x7D).
4
AVG
R/W
AVG = 1, Averaging on the temperature and voltage measurements is turned off. This allows
measurements on each channel to be made much faster.
5
ATTN
R/W
ATTN = 1, the ADT7463 removes the attenuators from the 2.5 V, V
CCP
, 5 V, and 12 V inputs.
The inputs can be used for other functions such as connecting up external sensors.
6
CONV
R/W
CONV = 1, the ADT7463 is put into a singlechannel ADC conversion mode. In this mode, the
ADT7463 can be made to read continuously from one input only, for example, Remote 1
temperature. It is also possible to start ADC conversions using an external clock on Pin 11 by
setting Bit 2 of Test Register 2 (Reg. 0x7F). This mode could be useful if, for example, users
wanted to characterize/profile CPU temperature quickly. The appropriate ADC channel is
selected by writing to Bits <7:5> of TACH1 min high byte register (Reg. 0x55).

SHDN
R/W
SHDN = 1, ADT7463 goes into shutdown mode. All PWM outputs assert low (or high
depending, on state of INV bit) to switch off all fans. The PWM current duty cycle registers read
0x00 to indicate that the fans are not being driven.
1. This register becomes readonly when the Configuration Register 1 Lock bit is set to 1. Further attempts to write to this register have no effect.
