Note 1. RES and peripheral function pins associated with P100, P101, P205, P206, P400, P401, P407 to P411 (total 12 pins).

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

Note 3. P100, P101, P205, P206, P400, P401, P407 to P411 (total 11 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.
