PRODUCTION DATA
Table 7-2 lists the correct termination of all unused pins.
PIN(1) | POTENTIAL | COMMENT |
---|---|---|
AVCC | DVCC | |
AVSS | DVSS | |
VREF | Open | |
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. |
P1.3/TDO P1.2/TDI P1.1/TMS P1.0/TCK |
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. |
