84 / 259 page  6.4 Pin Connectivity Requirements This section describes connectivity requirements for package balls that have specific connectivity requirements and unused package balls. Note All power balls must be supplied with the voltages specified in Section 7.5, Recommended Operating Conditions, unless otherwise specified . Note For additional clarification, "leave unconnected" or "no connect" (NC) means no signal traces can be connected to these device ball numbers. Table 6-74. Connectivity Requirements ALW BALL NUMBER AMC BALL NUMBER BALL NAME CONNECTION REQUIREMENTS D1 B10 B1 A11 MCU_ERRORn TRSTn Each of these balls must be connected to VSS through separate external pull resistors to ensure the inputs associated with these balls are held to a valid logic low level if a PCB signal trace is connected and not actively driven by an attached device. The internal pull-down can be used to hold a valid logic low level if no PCB signal trace is connected to the ball. E12 C11 E11 F20 A10 A11 B11 D9 B10 C9 E15 C10 D10 B11 EMU0 EMU1 MCU_RESETz RESET_REQz TCK TDI TMS Each of these balls must be connected to the corresponding power supply(1) through separate external pull resistors to ensure the inputs associated with these balls are held to a valid logic high level if a PCB signal trace is connected and not actively driven by an attached device. The internal pull-up can be used to hold a valid logic high level if no PCB signal trace is connected to the ball. A8 D10 B9 A9 B9 A10 E9 A9 MCU_I2C0_SCL MCU_I2C0_SDA WKUP_I2C0_SCL WKUP_I2C0_SDA Each of these balls must be connected to the corresponding power supply(1) through separate external pull resistors to ensure the inputs associated with these balls are held to a valid logic high level.
