REGISTER 23-26: BnSIDL: TX/RX BUFFER n STANDARD IDENTIFIER REGISTERS,
LOW BYTE IN RECEIVE MODE [0 ≤ n ≤ 5, TXnEN (BSEL0<n>) = 0]
(1)
R-x R-x R-x R-x R-x U-0 R-x R-x
SID2 SID1 SID0 SRR EXID —EID17EID16
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 7-5 SID2:SID0: Standard Identifier bits (if EXID = 0)
Extended Identifier bits EID20:EID18 (if EXID = 1).
bit 4 SRR: Substitute Remote Transmission Request bit (only when EXID = 1)
1 = Remote transmission request occurred
0 = No remote transmission request occurred
bit 3 EXID: Extended Identifier Enable bit
1 = Received message is an extended identifier frame (SID10:SID0 are EID28:EID18)
0 = Received message is a standard identifier frame
bit 2 Unimplemented: Read as ‘0’
bit 1-0 EID17:EID16: Extended Identifier bits
Note 1: These registers are available in Mode 1 and 2 only.
