• PWR = Power

• GND = Ground

• CAP = LDO Capacitor.

6. DSIS: The deselected input state (DSIS) indicates the state driven to the subsystem input (logic "0", logic

"1", or "pad" level) when the pin multiplexed signal function is not selected by MUXMODE.

• 0: Logic 0 driven to the subsystem input.

• 1: Logic 1 driven to the subsystem input.

• pad: Logic state of the pad is driven to the subsystem input.

• An empty box means Not Applicable.

7. BALL STATE DURING RESET (RX/TX/PULL): State of the terminal while MCU_PORz is asserted, where

RX defines the state of the input buffer, TX defines the state of the output buffer, and PULL defines the state

of internal pull resistors:

• RX (Input buffer)

– Off: The input buffer is disabled.

– On: The input buffer is enabled.

• TX (Output buffer)

– Off: The output buffer is disabled.

– Low: The output buffer is enabled and drives VOL.

• PULL (Internal pull resistors)

– Off: Internal pull resistors are turned off.

– Up: Internal pull-up resistor is turned on.

– Down: Internal pull-down resistor is turned on.

– NA: Not Applicable.

• An empty box means Not Applicable.

8. BALL STATE AFTER RESET (RX/TX/PULL): State of the terminal after MCU_PORz is deasserted, where

RX defines the state of the input buffer, TX defines the state of the output buffer, and PULL defines the state

of internal pull resistors:

• RX (Input buffer)

– Off: The input buffer is disabled.

– On: The input buffer is enabled.

• TX (Output buffer)

– Off: The output buffer is disabled.

– SS: The subsystem selected with MUXMODE determines the output buffer state.

• PULL (Internal pull resistors)

– Off: Internal pull resistors are turned off.

– Up: Internal pull-up resistor is turned on.

– Down: Internal pull-down resistor is turned on.

– NA: Not Applicable.

• An empty box means Not Applicable.

9. MUX MODE AFTER RESET: The value found in this column defines the default pin multiplexed signal

function after MCU_PORz is deasserted.

An empty box means Not Applicable.

10. I/O VOLTAGE VALUE: This column describes I/O operating voltage options of the respective power supply,

when applicable.

An empty box means Not Applicable.

For more information, see valid operating voltage range(s) defined for each power supply in Section 6.4,

Recommended Operating Conditions.

11. POWER: The power supply of the associated I/O, when applicable.
