The buffers, SID, EID, DLC, Data Field and Receive Status registers are located in DMA RAM.
See Definition for Bits 7-0, Controls Buffer n
TXENm: TX/RX Buffer Selection bit
1 = Buffer TRBn is a transmit buffer
0 = Buffer TRBn is a receive buffer
TXABTm: Message Aborted bit
1 = Message was aborted
0 = Message completed transmission successfully
TXLARBm: Message Lost Arbitration bit
1 = Message lost arbitration while being sent
0 = Message did not lose arbitration while being sent
TXERRm: Error Detected During Transmission bit
1 = A bus error occurred while the message was being sent
0 = A bus error did not occur while the message was being sent
TXREQm: Message Send Request bit
1 = Requests that a message be sent. The bit automatically clears when the message is successfully
0 = Clearing the bit to ‘0’ while set requests a message abort
RTRENm: Auto-Remote Transmit Enable bit
1 = When a remote transmit is received, TXREQ will be set
0 = When a remote transmit is received, TXREQ will be unaffected
TXmPRI<1:0>: Message Transmission Priority bits
11 = Highest message priority
10 = High intermediate message priority
01 = Low intermediate message priority
00 = Lowest message priority
