Legend:
H: High level
L: Low level
T: High impedance
keep: Input port becomes high-impedance (when DDR = 0 and PCR = 1, MOS input pull-ups
remain on), output port retains state
Notes: *1 With address outputs, the last address accessed is retained.
*2 As on-chip supporting modules are initialized, becomes an I/O port determined by DDR
and DR.
