<1> Up to 4 measuring functions can be simultneously active; the measured value
memory is read-out using a handshaking technique according to [4720], [4730].
<2> Index [n-1] --> encoder n (n = 1, 2, 3)
Index [0] --> encoder 1
Index [1] --> encoder 2
Index [2] --> encoder 3
<3> All other bits in the encoder control word must be 0.
<4> These measuring probe inputs only exist on the CU320.
