Notes 1. Digital or analog for each pin can be selected with the port mode control register x (PMCx) (can be set in 1-
bit unit).
2. Digital or analog for each pin can be selected with the A/D port configuration register (ADPC).
Remark Functions in parentheses in the above figure can be assigned via settings in the peripheral I/O redirection
register (PIOR). See Figure 5-8 Format of Peripheral I/O Redirection Register (PIOR).
