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.
