2. The relationship between pins and their alternate functions shown in this table indicates the relationship

when a 128-pin product is used. In other products, alternate functions might be assigned to different

pins, but even in this case, the PIOR×, POM××, PMCxx, PMxx, and Pxx set in the same way.

3. Functions in parentheses in the above table can be assigned via settings in the peripheral I/O

redirection register (PIOR).
