: High level
: Low level
: High impedance
: Input ports are in the high-impedance state (when DDR = 0 and PCR = 1, the input pull-up
* In the case of address output, the last address accessed is retained.
MOS remains on).
Output ports retain their previous state.
Depending on the pins, the on-chip peripheral modules may be initialized and the pins
may function as I/O ports determined by DDR and DR.
