Description
Interrupt Priority Grouping
This field determines the split of group priority from subpriority (see
Table 3-8 on page 141 for more information).
Software should not rely on the value of a reserved bit. To provide
compatibility with future products, the value of a reserved bit should be
preserved across a read-modify-write operation.
