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
SID<10:3>: Standard Identifier Filter bits (if EXIDEN = 0 )
Extended Identifier Filter bits, EID<28:21> (if EXIDEN = 1 ).
SID<2:0>: Standard Identifier Filter bits (if EXIDEN = 0 )
Extended Identifier Filter bits, EID<20:18> (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 ’
EID<17:16>: Extended Identifier Filter bits
