8.2.3 Bi-phase signal input circuits (RX0, RX1, RX2)
If using RX1, which has a built-in amplifier, as a coaxial input pin, malfunction may occur due to the influence of
the adjacent RX0 and RX2 input pins. To prevent them from influencing RX1, fix RX0 and RX2 to "L".
If, when RX1 is selected, the input signal to RX1 is temporarily open because of AC coupling, the RX0 and RX2
potential must be fixed. In this case, there are 5 bi-phase signal input pins that can be selected, RX1 and RX3 to RX
6.
If, when RX1 is selected, the input signal to RX1 is absolutely fixed to either "H" or "L", RX0 and RX2 handling is
not required. In this case, all 7 input pins are valid and can be used.
