included in Section 4.3, Signal Descriptions.

Table 4-29. Unused Balls Specific Connection Requirements

Balls

Connection Requirements

B21 / E22 / J5/ AA10

These balls must be connected to GND through an external pull

resistor if unused

J2 / G5 / G4 / L3 / L4 / AB10 / J3

These balls must be connect to the corresponding power supply

through an external pull resistor if unused

M19 / M20 / M21 / M22 / N22 / N21 / P19 / P18 / P20

These balls must be connected together to GND through a single

external 10k-ohm resistor 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.
