Note 1: Which function of the pin is used depends on how the P10 Peripheral Function Select Register is set.
Note 2: The DD input functions are effective depending on the settings of DD input pin select register (DDSEL). (For details, refer to
the Chapter 14, "Direct RAM Interface") To use the port as DD input pin, set the port direction for input.

Note 1: When not using this pin as CRX0 pin, always be sure to set the bit to "0."
Note: • The value of this register can only be modified when the corresponding P10 operation mode register bit = 0 (set for port).
Then set the corresponging P10 operation mode register bit to "1."
