Pin Definitions (continued)

Name	I/O			Description

VSS	Ground			Ground for the core of the device.
VSSQ	I/O Ground			Ground for the I/O circuitry.
TDO	JTAG serial output			Serial data-out to the JTAG circuit. Delivers data on the negative edge of TCK. If the
	Synchronous			JTAG feature is not being utilized, this pin should be left unconnected. This pin is not
				available on TQFP packages.
TDI	JTAG serial input			Serial data-In to the JTAG circuit. Sampled on the rising edge of TCK. If the JTAG
	Synchronous			feature is not being utilized, this pin can be left floating or connected to VDD through a pull
				up resistor. This pin is not available on TQFP packages.
TMS	JTAG serial input			Serial data-In to the JTAG circuit. Sampled on the rising edge of TCK. If the JTAG
	Synchronous			feature is not being utilized, this pin can be disconnected or connected to VDD. This pin
				is not available on TQFP packages.
TCK	JTAG-			Clock input to the JTAG circuitry. If the JTAG feature is not being utilized, this pin must
	Clock			be connected to VSS. This pin is not available on TQFP packages.
NC	–			No Connects. Not internally connected to the die. 18M, 36M, 72M, 144M, 288M, 576M
				and 1G are address expansion pins and are not internally connected to the die.
VSS/DNU	Ground/DNU			This pin can be connected to Ground or should be left floating.
