+ An array of two integers for configuring the chip measurement mode.
+ The first integer defines the bits 2..0 in the control register. In all
+ cases the internal temperature and supply voltage are measured. In
+ addition the following input measurements are enabled per mode:
+ 0: V1, V2, TR2
+ 1: V1-V2, TR2
+ 2: V1-V2, V3, V4
+ 3: TR1, V3, V4
+ 4: TR1, V3-V4
+ 5: TR1, TR2
+ 6: V1-V2, V3-V4
+ 7: V1, V2, V3, V4
+ The second integer defines the bits 4..3 in the control register. This
+ allows a subset of the measurements to be enabled:
+ 0: Internal temperature and supply voltage only
+ 1: TR1, V1 or V1-V2 only per mode
+ 2: TR2, V3 or V3-V4 only per mode
+ 3: All measurements per mode
