Note

The default muxmode is the mode at the release of the reset; also see the BALL RESET REL. MUXMODE column.

b. MUXMODE 1 through 7 are possible muxmodes for alternate functions. On each pin, some muxmodes are effectively used for alternate

functions, while some muxmodes are not used. Only MUXMODE values which correspond to defined functions should be used.

c. An empty box means Not Applicable.

5. TYPE: Signal type and direction:

• I = Input

• O = Output

• OD = Open drain terminal - Output

• IO = Input or Output

• IOD = Open drain terminal - Input or Output

• IOZ = Input, Output or Three-state terminal

• OZ = Output or Three-state terminal

• A = Analog

• PWR = Power

• GND = Ground

• CAP = LDO Capacitor.

6. BALL RESET STATE: The state of the terminal at power-on reset:

• DRIVE 0 (OFF): The buffer drives VOL (pulldown or pullup resistor not activated).

• DRIVE 1 (OFF): The buffer drives VOH (pulldown or pullup resistor not activated).

• OFF: High-impedance

• PD: High-impedance with an active pulldown resistor

• PU: High-impedance with an active pullup resistor

• An empty box means Not Applicable.

7. BALL RESET REL. MUXMODE: This muxmode is automatically configured at the release of the RESETSTATz and MCU_RESETSTATz signals.

An empty box means Not Applicable.

8. I/O VOLTAGE VALUE: This column describes the IO voltage value (the corresponding power supply).

An empty box means Not Applicable.

9. POWER: The voltage supply that powers the terminal IO buffers.

An empty box means Not Applicable.

10. HYS: Indicates if the input buffer has hysteresis:

• Yes: With hysteresis

• No: Without hysteresis

An empty box means No.

For more information, see the hysteresis values in Section 7.6, Electrical Characteristics.

11. BUFFER TYPE: This column describes the associated output buffer type

An empty box means Not Applicable.
