UART 16C550C
The UART chip, 16C550C, is an intelligent asynchronous controller capable of
supporting one full duplex channel that transfers data at
921.6 Kbps simultaneously.
To increase the overall data throughput, special features such as on-chip FIFO and
on-chip hardware flow control are used to reduce the number of interrupts to the on
board CPU and to prevent any loss of valuable data.
