The signals for index channel CH0 are connected up to
pins X1 and X2. Pins X3 to X6 are allocated to internal
channels CH1 and CH2 via MUXIN. INMODE can be
activated for referenced input signals; this then selects
X2 as the reference input. For output purposes INVZ
allows the index signal phase to be inverted.
