Serial Interface (USART)
The serial port is full duplex and can operate in four modes (one synchronous mode,
three asynchronous modes) as illustrated in
Table 8
.
For clarification some terms regarding the difference between “baud rate clock” and
“baud rate” should be mentioned. In the
asynchronous modes
the serial interfaces
require a clock rate which is 16 times the baud rate for internal synchronization.
Therefore, the baud rate generators/timers have to provide a “baud rate clock” (output
signal in
Figure 15
to the serial interface which - there divided by 16 - results in the
actual “baud rate”. Further, the abbreviation
f
OSC
refers to the oscillator frequency
(crystal or external clock operation).
The variable baud rates for modes 1 and 3 of the serial interface can be derived either
from timer 1 or from a dedicated baud rate generator (see
Figure 15
).
