Enhanced Extended Transparent Mode (MDS2-0 = ’100’ and SRA = ’1’).
If exmr.sra=1 then the receive data flow is controlled by start and stop characters. The
value of SAP1 is interpreted as start and TEI1 as stop (similar to the HDLC address
recognition). Each character bit which is used for comparison can be masked by a binary
“1” (i.e. it is not used for comparison) in SAP2 and TEI2, respectively.
The start character recognition works non-aligned, i.e. reception starts as soon as a start
character is detected anywhere in the serial data stream. After this start pattern has been
recognized the following data bits are byte aligned. As opposed to the start character,
the stop character is byte aligned.
Figure 17-16 Example
Note: It should be noted that the pattern of the stop character must not be contained in
Received bytes, including start and stop characters are stored in the receive fifo. In case
of several consecutive stop characters only the first is stored in the fifo. It is marked as
message end, so the uP gets an RME interrupt when the block containing the last
character is ready for readout in the fifo.
