The AMC7812 implements a technology to automatically cancel out the effect of series resistance caused
by the length of wire attached to any external remote temperature sensor. The resistance cancellation can
be disabled or enabled when the RC bit is cleared or set.
The conversion rate of the temperature data can also be set by adjusting the Temp-Conversion Rate
dropdown, displayed in
The GPIO + Temp page also features four (GPIO0 through GPIO3) general-purpose I/Os of the AMC7812
device as shown in

of the GPIO register. Press the Generate Write/Read button to write to or read from the GPIO pin.
