UART 16C550C

The  UART  chip, 

16C550C

,  is  an  intelligent  asynchronous  controller  capable  of

supporting one full duplex channel that simultaneously transfers data at 

921.6 Kbps

.

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
onboard CPU and to prevent any loss of valuable data.
