It is possible to choose which part of the incoming data stream is compared against the
stored MIDs. The register MIDC0 contains the Scan Start Position (Bit 0 to Bit 127). If
the Bit Counter detects the Scan Start Position the Control FSM enables the Scanner.
The register MIDC1 contains the number of bytes to scan (Byte 0 to Byte 3). During the
observation period, the Message ID Scanning is aborted immediately by the Master FSM
if symbol synchronization is lost or an EOM (End Of Message) is detected.
Example:
Start Selection: 0010001b
Number to scan: 00b, 01b, 10b, 11b
Figure 59
The starting position in this case is Bit 17. Depending on the number to scan, the
corresponding number of bytes is compared with the stored MIDs.
