Notes: 1. 3-State: High-impedance state
2. Prev. state: Previous state. Input ports are in the high-impedance state (with the MOS
pull-up on if PCR = 1). Output ports hold their previous output level.
3. I/O port: Direction depends on the data direction (DDR) bit. Note that these pins may
also be used by the on-chip supporting modules.
See section 5, "I/O Ports," for further information.
* On-chip supporting modules are initialized, so these pins revert to I/O ports according
to the DDR and DR bits.
