Note 1. RES and peripheral function pins associated with P303, P407 to P413, P511, P512, P514, P515, P708 to P715 (total 21 pins).

Note 2. P204 and P205 (total 2 pins)

Note 3. All input pins except for the peripheral function pins already described in the table. There is an item for each power supply voltage

for each port. Refer to the IO chapter for the power supply of the port.

Note 4. P303, P407 to P413, P511, P512, P514, P515, P708 to P715 (total 20 pins).

Note 5. All input pins except for the ports already described in the table. There is an item for each power supply voltage for each port. Refer

to the IO chapter for the power supply of the port.

Note 6. When VCC or VCC2 is less than 1.62 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.
