In single-bit applications, DUTT RX1 must be used. In two-bit applications, DUTT RX1 and DUTT RX2 must be used. In
four-bit applications, DUTT RX1, DUTT RX2, DUTT RX3, and DUTT RX4 must be used. In multi-terminal applications, the RX
signals from two or more remote terminals should be connected through OR gates in the FlexLogic and the resulting
signals should be configured as the
DUTT RX inputs.
