The message buffer memory map starts at an offset of 0x80 from the FlexCAN’s base address 1 or CAN1:
0x2000). The 512-byte message buffer space is fully used by the 32 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 8 bytes of data.

Buffer interrupt flag. Indicates a successful transmission/reception for the corresponding message buffer. If the
corresponding IMASKn bit is set, an interrupt request will be generated. The user must write a 1 to clear an interrupt
flag; writing 0 has no effect.
0 No such occurrence.
1 The corresponding buffer has successfully completed transmission or reception.
