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 used to control the filter event pins at the Extension Interface. A ‘1’ at the respective bit
position enables generation of a pulse at the related filter event pin with the duration of one
CLK_CAN_APB period in case the filter matches.
EFID2[5:0] defines the offset to the Rx Buffer Start Address RXBC.RBSA for storage of a matching
message.
