The Universal Asynchronous Receiver/Transmitter (UART) provides a full-duplex
asynchronous receiver/transmitter, i.e., it can transmit and receive simultaneously. It is
also receive-buffered, i.e., it can commence reception of a second byte before a
previously received byte has been read from the receive register. However, if the first
byte still has not been read by the time reception of the second byte is complete, one of
the bytes will be lost.
Features:
• Full-duplex asynchronous modes
• Receive buffered
• Multiprocessor communication
• Interrupt generation on the completion of a data transmission or reception
The UART can operate in the four modes as shown in
TXD and received on RXD.

Operating Mode
Mode 0: 8-bit shift register
Mode 1: 8-bit shift UART
Mode 2: 9-bit shift UART
Mode 3: 9-bit shift UART
There are several ways to generate the baud rate clock for the serial port, depending on
the mode in which it is operating. In mode 0, the baud rate for the transfer is fixed at
f
and can be configured to either f
either the underflow rate on the dedicated baud-rate generator, or by the overflow rate
on Timer 1.
