CAN 2.0B
— 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.

CANIDMR0–CANIDMR3) produces filter 0 to 3 hits. Similarly, the second filter bank
(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
never set.
