bit 7 bit 0
Legend: C = Writable bit, but only ‘0’ can be written to clear the bit
R = Readable bit W = Writable bit U = Unimplemented bit, read as ‘0’
-n = Value at POR ‘1’ = Bit is set ‘0’ = Bit is cleared x = Bit is unknown
bit 15-0 FLTENn: Enable Filter n to Accept Messages bits
1 = Enable Filter n
0 = Disable Filter n
