Table 4-2 lists the correct termination of all unused pins.
|ROSC||AVSS||Connect ROSC pin to AVSS when DCO is used in internal resistor mode|
|Px.0 to Px.7||Open||Switched to port function, output direction|
|Ax.0+ and Ax.0-||AVSS||Short unused analog input pairs and connect them to analog ground|
|RST/NMI||DVCC or VCC||47-kΩ pullup with 10 nF (or 2.2 nF(2)) pulldown|
|TEST||Open||This pin always has an internal pulldown enabled|
|P1.3/TDO||Open||The JTAG pins are shared with general-purpose I/O function (P1.x). If not being used, these should be switched to port function, output direction. When used as JTAG pins, these pins should remain open.|
