Reserved
For Tx 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 0b1110.

Initial Tx Code
the TouCAN module, copied from the DLC (data length code) 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 RTR (remote transmission request)
= 1, the frame is a remote frame and will be transmitted without 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.
The CPU controls access to this word entry field (16 bits).
NOT ACTIVE — message buffer is not active.
EMPTY — message buffer is active and empty.
FULL — message buffer is full.
OVERRUN — addtional 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.

Message buffer not ready for transmit.
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
frame, always.
Data frame to be transmitted only once, unconditionally, and
then only as a response to remote frame, always.
