EID15 EID14 EID13 EID12 EID11 EID10 EID9 EID8
bit 7 bit 0
Legend:
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 7-0 EID[15:8]: Extended Identifier bits
These bits hold bits 15 through 8 of the Extended Identifier for the received message
