Universal Asynchronous Receiver/Transmitter (UART) 16550 Transceiver IP performs serial-to-parallel conversion on data characters received from a peripheral UART device or a MODEM, and parallel-to-serial conversion on data characters received from the Host located inside the FPGA through a Lattice Memory-Mapped Interface (LMMI) or APB.
