I am facing a situation where I have one UART which is only used for Transmission. There is no requirement for RX functionality. I am using UART2. For this UART there are only two possible pin allocation for TXD & RXD. The first pair P0.10 & P0.11 is used for I2C functionality so I am left with P2.8 & P2.9 option only. Pin P2.9 is used as USB_CONNECT. As mentioned I have no RX functionality from the attached peripheral so I intend to use its TXD to do the transmission task and would like to have no assignment for RXD2 functionality. Is it possible to have UART without RXD pin assignment ?
