This section describes connectivity requirements for package balls that have specific connectivity requirements and unused package balls.
All power balls must be supplied with the voltages specified in the Recommended Operating Conditions section, unless otherwise specified in Signal Descriptions.
For additional clarification, "leave unconnected" or "no connect" (NC) means no signal traces can be connected to these device ball number.
Table 5-118 shows the connectivity requirements for specific signals by ball name and ball number.

Table 5-119 shows the specific connection requirements for the RESERVED ball numbers on the device.
For additional clarification, "left unconnected" or "no connect" (NC) means no signal traces can be connected to these device ball numbers.
| BALL NUMBERS | CONNECTION REQUIREMENTS |
|---|---|
| E28 / F27 / J29 / L28 / L29 / L30 / M30 / AH4 / AH7 / AH8 | RESERVED. These balls must be left unconnected. |
All other unused signal balls without Pad Configuration Register can be left unconnected.
All other unused signal balls with a Pad Configuration Register can be left unconnected with their multiplexing mode set to GPIO input and internal pulldown resistor enabled.
Unused balls are defined as those which only connect to a PCB solder pad. This is the only use case where internal pull resistors are allowed as the only source/sink to hold a valid logic level.
Any balls connected to a via, test point, or PCB trace are considered used and must not depend on the internal pull resistor to hold a valid logic level.
Internal pull resistors are weak and may not source enough current to maintain a valid logic level for some operating conditions. This may be the case when connected to components with leakage to the opposite logic level, or when external noise sources couple to signal traces attached to balls which are only pulled to a valid logic level by the internal resistor. Therefore, external pull resistors may be required to hold a valid logic level on balls with external connections.
