.

Fixed priority of Master x for accessing the selected slave. The higher the number, the higher the priority.

All the masters programmed with the same MxPR value for the slave make up a priority pool.

Round-Robin arbitration is used inside the lowest (MxPR = 0) and highest (MxPR = 3) priority pools.

Fixed priority is used inside intermediate priority pools (MxPR = 1) and (MxPR = 2).
