description:
33
+
Value in micro Ohms of the shunt resistor connected between
34
+
the SENSE+ and SENSE- inputs, across which the current is measured.
35
+
Value is needed to compute the scaling of the measured current.

description:
42

READ/INT input pin to control the current state of the device, either in

the INTEGRATE state when driven high, or in the READ state when driven low.
44
+
When not connected the pin is floating and it can be overridden by the
45

INT_EN register bit after asserting the READ/INT_OVR register bit.
