Legend
H: High
L: Low
T: High-impedance state
kept: Input ports are in the high-impedance state (when DDR = 0 and PCR = 1, input pull-up
MOSs remain on).
Output ports maintain their previous state.
Depending on the pins, the on-chip peripheral modules may be initialized and the I/O port
function determined by DDR and DR used.
DDR: Data direction register
Note:* In the case of address output, the last address accessed is retained.
