Remarks 1. ï‚´: Don't care
PIORxx: Peripheral I/O redirection register
POMxx: Port output mode register
PMCxx: Port mode control register
PMxx: Port mode register
Pxx: Port output latch
2. The relationship between pins and their alternate functions shown in this table indicates the relationship
when a 100-pin product is used. In other products, alternate functions might be assigned to different
pins, but even in this case, the PIORxx, POMxx, 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 are described after the last table.)
