PIOR×: Peripheral I/O redirection register
POM××: Port output mode register
PMC××: Port mode control register
PM××: Port mode register
P××: Port output latch
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).
(The Notes 1, 3 are described after the last table.)
