• HYB POTT RX1 through HYB POTT RX4: These settings allow the user to select the FlexLogic operands that repre-
sent the receive signals for the scheme. Typically input contacts interfacing with a signaling system are used. In single-
bit applications, HYB POTT RX1 must be used. In two-bit applications, HYB POTT RX1 and HYB POTT RX2 must be used. In
four-bit applications,
HYB POTT RX1, HYB POTT RX2, HYB POTT RX3, and HYB POTT RX4 must be used.
