1. The corresponging I/O stage is selected via bit (3:0) of control word 5.
2. VBy is selected in control word via bits SELES(3:0). VB1 measurements apply to SELES(3:0) = 0x0...0x3,
VB2 measurements apply to SELES(3:0) = 0x4...0x7, VB3 measurements apply to SELES(3:0) = 0x8...0xB
and VB4 measurements apply to SELES(3:0) = 0xC...0xF.
