Notes: • During processor mode, settings of this register have no effect, and the ports function as external bus interface signal

pins (DB0-DB7).

• The value of this register can only be modified when the corresponding P0 operation mode register bit = 0 (set for port).

Then set the corresponging P0 operation mode register bit to "1."

• During single-chip mode, selecting the external bus interface function is prohibited.
