SID: Standard Identifier Filter bits <10:3>
These bits hold the filter bits to be applied to bits <10:3> of the Standard Identifier portion of a
received message
Legend:
R = Readable bit
-n = Value at POR
W = Writable bit
U = Unimplemented bit, read as ‘0’
‘0’ = Bit is cleared x = Bit is unknown
‘1’ = Bit is set
