–

IO = Input or Output

–

D = Open drain

–

DS = Differential Signaling

–

A = Analog

–

PWR = Power

–

GND = Ground

–

CAP = LDO Capacitor

7. 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

8. BALL RESET REL. STATE: The state of the terminal at the deactivation of the rstoutn signal (also

mapped to the PRCM SYS_WARM_OUT_RST signal).

–

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

–

drive clk (OFF): The buffer drives a toggling clock (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

NOTE

For more information on the CORE_PWRON_RET_RST reset signal and its reset sources,

see the Power Reset and Clock Management / PRCM Reset Management Functional

Description section of the Device TRM.

9. BALL RESET REL. MUXMODE: This muxmode is automatically configured at the release of the

rstoutn signal (also mapped to the PRCM SYS_WARM_OUT_RST signal).

10. I/O VOLTAGE VALUE: This column describes the IO voltage value (VDDS supply).

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

12. HYS: Indicates if the input buffer is with hysteresis:

–

Yes: With hysteresis

–

No: Without hysteresis

An empty box means "Yes".

NOTE

For more information, see the hysteresis values in Section 5.6, Electrical Characteristics.

13. BUFFER TYPE: Drive strength of the associated output buffer.

NOTE

For programmable buffer strength:

–

The default value is given in Table 4-2.

–

A note describes all possible values according to the selected muxmode.

14. PULLUP / PULLDOWN TYPE: Denotes the presence of an internal pullup or pulldown resistor.

Pullup and pulldown resistors can be enabled or disabled via software.

15. DSIS: The deselected input state (DSIS) indicates the state driven on the peripheral input (logic "0",

logic "1", or "PIN" level) when the peripheral pin function is not selected by any of the PINCNTLx

registers.
