Serial Interface (USART)
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 4 modes (one synchronous
and three asynchronous) as illustrated in
Table 6
.
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”.
The baudrates in Mode 1 and 3 are determined by the timer overflow rate. These baudrates can be
determined by Timer 1 or by Timer 2 or both (one for transmit, the other for receive).
