P2 to P0: Priority setting bits
Determines priority of message. The smaller the priority value, the higher the priority.

Note:
The 1-byte header mode is not selected even if “1” is set to “H” bit.
The 3-byte header mode is always selected.
In the MSM6636/6636B, the “H” bit is not used for selective control of the number of header bytes. However,
since “0” has priority over “1”, the priority control depends on the bit value in the “H” bit, that is, the “H” bit
can be used as “P3” priority setting bit.
