Serial Interface (UART)
The serial port is a full duplex port capable of simultaneous transmit and receive
functions. It is also receive-buffered; it can commence reception of a second byte before
a previously-received byte has been read from the receive register. The serial port can
operate in 3 modes as illustrated in Table 10.
For clarification, some terms regarding the difference between “baudrate clock“ and
“baudrate“ should be mentioned.
The serial interface requires a clock rate which is 16 times the baudrate for internal
synchronization. Therefore, the baudrate generators must provide a “baudrate clock“ to
the serial interface which divides it by 16, thereby resulting in the actual “baudrate“.
