Asynchronous Receiver
Figure 25-10. Bit Resynchronization
If the USART is configured in an asynchronous operating mode (MR.SYNC = 0), the receiver will
oversample the RXD input line by either 8 or 16 times the baud rate clock, as selected by the
Oversampling Mode bit (MR.OVER). If the line is zero for half a bit period (four or eight consecu-
tive samples, respectively), a start bit will be assumed, and the following 8th or 16th sample will
determine the logical value on the line, in effect resulting in bit values being determined at the
middle of the bit period.
The number of data bits, endianess, parity mode, and stop bits are selected by the same bits
and fields as for the transmitter (MR.CHRL, MODE9, MSBF, PAR, and NBSTOP). The synchro-
nization mechanism will only consider one stop bit, regardless of the used protocol, and when
the first stop bit has been sampled, the receiver will automatically begin looking for a new start
bit, enabling resynchronization even if there is a protocol miss-match.
