7.6 Connection of Unused Pins

Table 7-4 lists the correct termination of unused pins.

Table 7-4 Connection of Unused Pins
PIN(1)POTENTIALCOMMENT
Px.0 to Px.7OpenSwitched to port function, output direction (PxDIR.n = 1)
RST/NMIDVCC47-kΩ pullup or internal pullup selected with 10-nF (or 1.1-nF) pulldown(2)
TESTOpenThis pin always has an internal pull-down enabled.
(1) Any unused pin with a secondary function that is shared with general-purpose I/O should follow the Px.0 to Px.7 unused pin connection guidelines.
(2) The pulldown capacitor should not exceed 1.1 nF when using MCUs with Spy-Bi-Wire interface in Spy-Bi-Wire mode with TI tools like FET interfaces or GANG programmers.
