Table 24. JTAG Signals

	Signal	Recommendations	Reason/Impact

	TCK	If not used for JTAG, leave as No Connect	Internal pull-up

	TDI	If not used for JTAG, leave as No Connect	Internal pull-up

	TDO	If not used for JTAG, leave as No Connect	Internal pull-up

	TMS	If not used for JTAG, leave as No Connect	Internal pull-up

	TRST#	Connect to ground via a 1KΩ pulldown resistor.	If TAP interface is not used this
	TRST#	Connect to ground via a 1KΩ pulldown resistor.	should be tied to ground.
			should be tied to ground.
