REGISTER 27-6: TXBnSIDH: TRANSMIT BUFFER ‘n’ STANDARD IDENTIFIER REGISTERS,
HIGH BYTE [0  n  2]
R/W-x R/W-x R/W-x R/W-x R/W-x R/W-x R/W-x R/W-x
SID10 SID9 SID8 SID7 SID6 SID5 SID4 SID3
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
SID<10:3>: Standard Identifier bits (if EXIDE (TXBnSIDL<3>) = 0)
Extended Identifier bits, EID<28:21> (if EXIDE =
1).

-n = Value at POR ‘1’ = Bit is set ‘0’ = Bit is cleared x = Bit is unknown
bit 7-5
SID<2:0>: Standard Identifier bits (if EXIDE (TXBnSIDL<3>) = 0)
Extended Identifier bits, EID<20:18> (if EXIDE =
1).

Unimplemented: Read as ‘0’
bit 3
EXIDE: Extended Identifier Enable bit
1 = Message will transmit extended ID, SID<10:0> become EID<28:18>
0 = Message will transmit standard ID, EID<17:0> are ignored
