Note 1. RES and peripheral function pins associated with Ports P205, P206, P400, P401, P407 to P415, and P708（total 15 pins).

Note 2. All input pins except for the peripheral function pins already described in the table.

Note 3. Ports P205, P206, P400, P401, P407 to P415, and P708（total 14 pins).

Note 4. All input pins except for the ports already described in the table.

Note 5. When VCC is less than 2.7 V, the input voltage of 5 V-tolerant ports should be less than 3.6 V, otherwise breakdown may occur

because 5 V-tolerant ports are electrically controlled so as not to violate the break down voltage.
