Note 1. SCL0_C, SDA0_C, SCL0_D, SDA0_D, SCL0_E, SDA0_E, SCL0_F, SDA0_F, SCL1_C, SDA1_C, SCL1_D, SDA1_D, SCL1_E,

SDA1_E (total 14 pins). This is the value when IIC function is selected.

Note 2. SCL0_A, SDA0_A, SCL0_B, SDA0_B, SCL1_A, SDA1_A, SCL1_B, SDA1_B (total 8 pins). This is the value when IIC function is

selected.

Note 3. RES and peripheral function pins associated with PA12 to PA15, PB03, PB05 to PB09, PC10 to PC12, PC14, PC15, PD00 to PD07,

PE00, and PE01 (total 26 pins).

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

Note 5. PA12 to PA15, PB03, PB05 to PB09, PC10 to PC12, PC14, PC15, PD00 to PD07, PE00, and PE01 (total 25 pins).

Note 6. All input pins except for the ports already described in the table.

Note 7. 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.
