21.3.2.9 Message Buffer Structure
The message buffer memory map starts at an offset of 0x80 from the FlexCAN’s base address
(CAN0: 0x1C_0000 or CAN1: 0x1F_0000). The 256-byte message buffer space is fully used by
the 16 message buffer structures.
Each message buffer consists of a control and status field that configures the message buffer, an
identifier field for frame identification, and up to eight bytes of data.
