Registers RXF6SIDH:RXF15SIDH are available in Mode 1 and 2 only.
Registers RXF6SIDL:RXF15SIDL are available in Mode 1 and 2 only.
In Mode 0, this bit must be set/cleared as required, irrespective of corresponding mask register value.
Message Acceptance Filters
and Masks
SID10:SID3: Standard Identifier Filter bits (if EXIDEN = 0)
Extended Identifier Filter bits EID28:EID21 (if EXIDEN = 1).
SID2:SID0: Standard Identifier Filter bits (if EXIDEN = 0)
Extended Identifier Filter bits EID20:EID18 (if EXIDEN = 1).
Unimplemented: Read as ‘0’
EXIDEN: Extended Identifier Filter Enable bit
1 = Filter will only accept extended ID messages
0 = Filter will only accept standard ID messages
Unimplemented: Read as ‘0’
