Control Configuration 3 Register (Read/Write)
[Address = 1Ah]
This configuration register is an 8-bit read/write register that is
used to set up some of the operating modes of the ADT7411.

Function
In single-channel mode, these bits select between V
the internal temperature sensor, external temperature
sensor/AIN1, AIN2 to AIN8 for conversion. The default is V
0000 = V
0001 = Internal Temperature Sensor.
0010 = External Temperature Sensor/AIN1. (Bit C1 and
Bit C2 of Control Configuration 1 affect this selection.)
0011 = AIN2.
0100 = AIN3.
0101 = AIN4.
0110 = AIN5.
0111 = AIN6.
1000 = AIN7.
1001 = AIN8.
1010 to 1111 = Reserved.
Selects between single-channel and round robin
conversion cycle. Default is round robin.
0 = Round robin.
1 = Single-channel.
Default condition is to average every measurement on
all channels 16 times. This bit disables this averaging.
Channels affected are temperature, analog inputs, and V
0 = Enable averaging.
1 = Disable averaging.
SMBus timeout on the serial clock puts a 25 ms limit on
the pulse width of the clock, ensuring that a fault on the
master SCL does not lock up the SDA line.
0 = Disable SMBus timeout.
1 = Enable SMBus timeout.
Software Reset. Setting this bit to a 1 causes a software
reset. All registers reset to their default settings.

Interrupt Mask 1 Register (Read/Write) [Address = 1Dh]
This mask register is an 8-bit read/write register that can be
used to mask out any interrupts that can cause the INT/ INT pin
to go active.
