Data
For transmit message buffers, upon read, the BUSY bit should be ignored.
When a matching remote request frame is detected, the code for such a message buffer is changed to be 1110.

identifier field of the frame on the CAN bus.
Refer to
Length (in bytes) of the Rx data stored in offset 0x6 through 0xD of the buffer. This field is written by
the FlexCAN module, copied from the data length code (DLC) field of the received frame.
Length (in bytes) of the data to be transmitted, located in offset 0x6 through 0xD of the buffer. This
field is written by the CPU, and is used as the DLC field value. If remote transmission request (RTR))
= 1, the frame is a remote frame and will be transmitted without the data field, regardless of the value
in Tx length.
This field can store up to eight data bytes for a frame. For Rx frames, the data is stored as it is
received from the bus. For Tx frames, the CPU provides the data to be transmitted within the frame.
This word entry field (16 bits) should not be accessed by the CPU.
NOT ACTIVE — message buffer is not active.
EMPTY — message buffer is active and empty.
FULL — message buffer is full.
OVERRUN — second frame was received into a full
buffer before the CPU read the first one.
BUSY — message buffer is now being filled with a new
receive frame. This condition will be cleared within 20
cycles.

Data frame to be transmitted once, unconditionally.
Remote frame to be transmitted once, and message buffer
becomes an Rx message buffer for data frames.
Data frame to be transmitted only as a response to a remote
