25.3.2
The message buffer memory map starts at an offset of 0x80 from the FlexCAN’s base address
(0x1C_0000). The 256-byte message buffer space is fully used by the 16 message buffer structures.

Message Buffer Memory Map
message buffer.
Contains a fixed recessive bit, used only in extended format. Should be set to one by the user for
Tx buffers. It will be stored as received on the CAN bus for Rx buffers. This is a bit in the ID HIGH
word of the message buffer.
If extended format frame is used, this field should be set to one. If zero, standard format frame
should be used. This is a bit in the ID HIGH word of the message buffer.
This bit is located in the least significant bit of the ID LOW word of the message buffer;
0 Data Frame
1 Remote Frame.
Bits [14:0] of the extended identifier, located in the ID LOW word of the message buffer.
Contains bits [28:18] of the identifier, located in the ID HIGH word of the message buffer. The four
least significant bits in this register (corresponding to the IDE bit and ID[17:15] for an extended
identifier message) must all be written as logic zeros to ensure proper operation of the FlexCAN.
Remote Transmission Request. This bit is located in the ID HIGH word of the message buffer.
0 data frame
1 remote frame.
If the FlexCAN transmits this bit as a one and receives it as a zero, an “arbitration loss” is
indicated. If the FlexCAN transmits this bit as a zero and receives it as a one, a bit error is
indicated.
If the FlexCAN transmits a value and receives a matching response, a successful bit transmission
is indicated.
The 16-bit time stamp, located in the ID LOW word of the message buffer, is not needed for
standard format, and is used in a standard format buffer to store the 16-bit value of the
free-running timer. The timer value is captured at the beginning of the identifier field of the frame
on the CAN bus.
