Note 1: Read-modify-write is prohibited for P0CR.
Note 2: When functioning as a data bus (D0 to D7), P0CR is cleared to 0.

output using the control register P0CR. Resetting resets all bits of the output latch P0, the
control register P0CR to 0 and sets port 0 to input mode. In addition to functioning as a
general-purpose I/O port, port 0 can also function as an data bus (D0 to D7).
