4.4 Connection of Unused Pins

Table 4-5 lists the correct termination of unused pins.

Table 4-5 Connection of Unused Pins(1)

PIN POTENTIAL COMMENT
AVCC DVCC
AVSS DVSS
Px.y Open Switched to port function, output direction (PxDIR.n = 1). Px.y represents port x and bit y of port x (for example, P1.0, P1.1, P2.2, PJ.0, PJ.1)
XIN DVSS For dedicated XIN pins only. XIN pins with shared GPIO functions should be programmed to GPIO and follow Px.y recommendations.
XOUT Open For dedicated XOUT pins only. XOUT pins with shared GPIO functions should be programmed to GPIO and follow Px.y recommendations.
LCDCAP DVSS
RST/NMI DVCC or VCC 47-kΩ pullup or internal pullup selected with 10-nF (2.2 nF) pulldown(2)
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 being used, these should be switched to port function, output direction (PJDIR.n = 1). 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.y unused pin connection guidelines.
(2) The pulldown capacitor should not exceed 2.2 nF when using devices with Spy-Bi-Wire interface in Spy-Bi-Wire mode or in 4-wire JTAG mode with TI tools such as FET interfaces or GANG programmers.
