1.1.2 UARTx TX and RX Not Available as CLB Inputs

The UART1 and UART2 TX and RX selections are not available as inputs to the CLB module. When the user selects the TX1, TX2, RX1, or RX2 input selections, the respective U1TXIF, U2TXIF, U1RXIF, and U2RXIF interrupt signals are internally selected instead.

Work Around

If the TX1 and/or TX2 signals are necessary, they can be routed through a CLC as inputs to the CLB.
If the RX1 and/or RX2 signals are necessary, they can be routed through CLBINxPPS as inputs to the CLB.
