Table 4-2 lists the correct termination of all unused pins.
|ROSC||AVSS||Connect the ROSC pin to AVSS when the DCO is used in internal resistor mode.|
|Px.0 to Px.7||Open||Set 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.|
|Open||The JTAG pins are shared with general-purpose I/O function (P1.x). If these pins are not used, set them to port function and output direction. When used as JTAG pins, leave these pins open.|
