Bits 28:0 – EFID2[28:0] Extended Filter ID 2

This bit field has a different meaning depending on the configuration of EFEC.

1) EFEC = “001” ... “110” Second ID of standard ID filter element.

2) EFEC = “111” Filter for Rx Buffers or for debug messages.

EFID2[10:9] decides whether the received message is stored into an Rx Buffer or treated as message A, B, or C of the debug message sequence.

00 = Store message into an Rx Buffer

01 = Debug Message A

10 = Debug Message B

11 = Debug Message C

EFID2[8:6] is reserved for future usage. EFID2[5:0] defines the offset to the Rx Buffer Start Address RXBC.RBSA for storage of a matching message.
