Overview
into parallel data, then are stored in the Receive FIFO buffer. Parallel data stored in the FIFO buffer are
fetched by either CPU or DMA transfer.
converted into serial data, then are output as a TXD signal.
Data Format
During reception, serial data that are input as an RXD signal from an external source are converted
During transmission, parallel data written to the Transmit FIFO buffer by CPU or DMA transfer are
