Freescale’s Scalable Controller Area Network (S12MSCANV3)
18.3.3.4
This register defines the local priority of the associated message buffer. The local priority is used for the
internal prioritization process of the MSCAN and is defined to be highest for the smallest binary number.
The MSCAN implements the following internal prioritization mechanisms:
In cases of more than one buffer having the same lowest priority, the message buffer with the lower index
number wins.

Reset:
All transmission buffers with a cleared TXEx flag participate in the prioritization immediately
before the SOF (start of frame) is sent.
The transmission buffer with the lowest local priority field wins the prioritization.

Data Length Code Bits — The data length code contains the number of bytes (data byte count) of the respective
message. During the transmission of a remote frame, the data length code is transmitted as programmed while
the number of transmitted data bytes is always 0. The data byte count ranges from 0 to 8 for a data frame.
