REGISTER 27-9: TXBnEIDL: TRANSMIT BUFFER ‘n’ EXTENDED IDENTIFIER REGISTERS,
LOW 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
EID7 EID6 EID5 EID4 EID3 EID2 EID1 EID0
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<7:0>: Extended Identifier bits (not used when transmitting standard identifier message)
REGISTER 27-10: TXBnDm: TRANSMIT BUFFER ‘n’ DATA FIELD BYTE ‘m’ REGISTERS
[0  n  2, 0  m  7]
R/W-x R/W-x R/W-x R/W-x R/W-x R/W-x R/W-x R/W-x
TXBnDm7 TXBnDm6 TXBnDm5 TXBnDm4 TXBnDm3 TXBnDm2 TXBnDm1 TXBnDm0
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
TXBnDm<7:0>: Transmit Buffer n Data Field Byte m bits (where 0 n < 3 and 0 m < 8)
Each transmit buffer has an array of registers. For example, Transmit Buffer 0 has 7 registers: TXB0D0
to TXB0D7.
