Description
AIN1 = 0, Speed of 3-wire fans measured using the TACH output from the fan.
AIN1 = 1, Pin 6 is reconfigured to measure the speed of 2-wire fans using an external
sensing resistor and coupling capacitor.
AIN voltage threshold is set via Configuration Register 4 (Reg. 0x7D).
AIN2 = 0, Speed of 3-wire fans measured using the TACH output from the fan.
AIN2 = 1, Pin 7 is reconfigured to measure the speed of 2-wire fans using an external
sensing resistor and coupling capacitor.
AIN voltage threshold is set via Configuration Register 4 (Reg. 0x7D).
AIN3 = 0, Speed of 3-wire fans measured using the TACH output from the fan.
AIN3 = 1, Pin 4 is reconfigured to measure the speed of 2-wire fans using an external
sensing resistor and coupling capacitor.
AIN voltage threshold is set via Configuration Register 4 (Reg. 0x7D).
AIN4 = 0, Speed of 3-wire fans measured using the TACH output from the fan.
AIN4 = 1, Pin 9 is reconfigured to measure the speed of 2-wire fans using an external
sensing resistor and coupling capacitor.
AIN voltage threshold is set via Configuration Register 4 (Reg. 0x7D).
AVG = 1, Averaging on the temperature and voltage measurements is turned off. This
allows measurements on each channel to be made much faster.
ATTN = 1, the ADT7460 removes the attenuators from the 2.5 V input. The input can
be used for other functions such as connecting up external sensors.
CONV = 1, the ADT7460 is put into a single-channel ADC Conversion Mode. In this
mode, the ADT7460 can be made to read continuously from one input only, e.g.,
Remote 1 Temperature. It is also possible to start ADC conversions using an external
clock on Pin 6 by setting Bit 2 of Test Register 2 (Reg. 0x7F). This mode could be
useful if, for example, you 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 (0x55).

SHDN = 1, ADT7460 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.

This register becomes read-only when the Configuration Register 1 Lock bit is set to 1. Any further attempts to write to this register will have no effect.
