37      The first integer defines the bits 2..0 in the control register. In all
38      cases the internal temperature and supply voltage are measured. In
39      addition the following input measurements are enabled per mode:

42      b[2:0] | Mode [2:0] | Mode Description
43         0   |  0 0 0     | V1, V2, TR2 (Default)

52      The second integer defines the bits 4..3 in the control register. This
53      allows a subset of the measurements to be enabled:
