PIN POTENTIAL COMMENT
AVCC DVCC
AVSS DVSS
Px.0 to Px.7 Open Set to port function, output direction (PxDIR.n = 1)
R33/LCDCAP DVSS or DVCC If the pin is not used, it can be tied to either supply.
RST/NMI DVCC or VCC 47-kΩ pullup or internal pullup selected with 2.2-nF (10-nF(2)) pulldown
PJ.0/TDO
PJ.1/TDI
PJ.2/TMS
PJ.3/TCK		 Open The JTAG pins are shared with general-purpose I/O function (PJ.x). If not used as JTAG pins, these pins should be switched to port function, output direction. When used as JTAG pins, these pins should remain open.
TEST Open This pin always has an internal pulldown 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 2.2 nF when using devices in Spy-Bi-Wire mode or in 4-wire JTAG mode with TI tools like FET interfaces or GANG programmers. If JTAG or Spy-Bi-Wire access is not needed, up to a 10-nF pulldown capacitor may be used.
