Extended Identiﬁer

Standard Identiﬁer

— The 14 most signiﬁcant bits of the extended identiﬁer plus the SRR and IDE bits of CAN 2.0B

— The 11 bits of the standard identiﬁer, the RTR and IDE bits of CAN 2.0A/B messages.

Eight identiﬁer acceptance ﬁlters, each to be applied to the ﬁrst 8 bits of the identiﬁer. This mode

implements eight independent ﬁlters for the ﬁrst 8 bits of a CAN 2.0A/B compliant standard

identiﬁer or a CAN 2.0B compliant extended identiﬁer.

(CANIDAR4–CANIDAR7, CANIDMR4–CANIDMR7) produces ﬁlter 4 to 7 hits.

Closed ﬁlter. No CAN message is copied into the foreground buffer RxFG, and the RXF ﬂag is
