This section describes the connection requirements of the unused and reserved balls.
The following balls are reserved: K20, L19, G20
These balls must be left unconnected.
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 4.3, Signal Descriptions.
|Y12 / AC11 / L22 / AC10 / AB10 / AD22 / Y24 / V24 / R24||These balls must be connected to GND through an external pull resistor if unused.|
|K21 / L24 / K24 / G22 / G23 / L21 / G21 / F23 / AE22 / Y25 / V25 / R25||These balls must be connect to the corresponding power supply through an external pull resistor if unused.|
|F20 (vpp)||This ball must be left unconnected if unused.|
All other unused signal balls with a Pad Configuration register can be left unconnected with their internal pullup or pulldown resistor enabled.
All other unused signal balls without a Pad Configuration register can be left unconnected.
