Terminal Configuration and Functions

The following list describes the table column headers:

1. BALL NUMBER: Ball numbers on the bottom side associated with each signal on the bottom.

2. BALL NAME: Mechanical name from package device (name is taken from muxmode 0).

3. SIGNAL NAME: Names of signals multiplexed on each ball (also notice that the name of the ball is the

signal name in muxmode 0).

NOTE

Table 4-1, Pin Attributes, does not take into account the subsystem multiplexing signals.

Subsystem multiplexing signals are described in Section 4.3, Signal Descriptions.

4. MUXMODE: Multiplexing mode number:

a. MUXMODE 0 is the primary muxmode. The primary muxmode is not necessarily the default

muxmode.

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. Bootstrap are Special Configuration Pins, latched on rising edge of PORn / RESETFULLn. These

are not programable MUXMODE.

d. An empty box means Not Applicable.

5. TYPE: This column describes functionality of the pin when configured for the given mux mode. It does

not represent all capabilities of the pin, and as such, there may be other mux mode configurations

where these pins operate as a push-pull driver:

–

I = Input

–

O = 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.

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

chapter Device Configuration in the device TRM.

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

rstoutn signal.

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:
