2-Byte Organized Message ID:
In this mode two bytes are merged to define an ID Pattern. Up to 10 patterns are
possible.

ID Position Configuration:
It is possible to choose which part of the incoming data stream is compared against the
stored MIDs. The register x_MIDC0 contains the Scan Start Position. If the Bit Counter
detects the Scan Start Position, the Control FSM enables the Scanner. The register
x_MIDC1 contains the number of bytes to scan. During the observation period, the
