NOTE

All unused power supply balls must be supplied with the voltages specified in the

Section 5.4, Recommended Operating Conditions, unless alternative tie-off options are

included in Section 4.4, Signal Descriptions.

Table 4-1. Unused Balls Specific Connection Requirements

BALLS

CONNECTION REQUIREMENTS

These balls must be connected to GND through an external pull

AE15 / AC15 / AE14 / D20 / AD17 / AC16 / V27

resistor if unused

These balls must be connect to the corresponding power supply

E20 / D21 / E23 / C20 / C21 / AF14 / V28 / F18

through an external pull resistor if unused

AB17

These balls must be connected to F22 (porz) if unused

NOTE

All other unused signal balls with a Pad Configuration Register can be left unconnected with

their internal pullup or pulldown resistor enabled.

NOTE

All other unused signal balls without Pad Configuration Register can be left unconnected.

Ball Characteristics

Table 4-2 describes the terminal characteristics and the signals multiplexed on each ball. The following list

describes the table column headers:

1. BALL NUMBER: Ball number(s) 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 4-2 does not take into account the subsystem multiplexing signals. Subsystem

multiplexing signals are described in Section 4.4, Signal Descriptions.

NOTE

In the Driver off mode, the buffer is configured in high-impedance.

NOTE

In some cases Table 4-2 may present more than one signal name per muxmode for the

same

ball.

via

CTRL_CORE_PAD_* register.

All other signals are virtual functions that present alternate multiplexing options. This virtual

are

controlled

via

CTRL_CORE_ALT_SELECT_MUX

CTRL_CORE_VIP_MUX_SELECT register. For more information on how to use this options,

please refer to Device TRM, Chapter Control Module, Section Pad Configuration Registers.

4. 18/16: This column shows if the functionality is applicable for AM5718 / AM5716 devices. Note that the

ball characteristics table presents the functionality of AM5718 device. If the cell is empty it means that

the signal is available in all devices.
