AMD Sempron™ Processor Model 10 with 256K L2 Cache Data Sheet

31994A—1 August 2004

INTR Pin	INTR is an input from the system that causes the processor to
	start an interrupt acknowledge transaction that fetches the
	8-bit interrupt vector and starts execution at that location.
JTAG Pins	TCK, TMS, TDI, TRST#, and TDO are the JTAG interface.
	Connect these pins directly to the motherboard debug
	connector. Pull TDI, TCK, TMS, and TRST# up to VCC_CORE with
	pullup resistors.
K7CLKOUT and	K7CLKOUT and K7CLKOUT# are each run for two to three
K7CLKOUT# Pins	inches and then terminated with a resistor pair: 100 ohms to
	VCC_CORE and 100 ohms to VSS. The effective termination
	resistance and voltage are 50 ohms and VCC_CORE /2.
Key Pins	These 16 locations are for processor type keying for forwards
	and backwards compatibility (G7, G9, G15, G17, G23, G25, N7,
	Q7, Y7, AA7, AG7, AG9, AG15, AG17, AG27, and AG29).
	Motherboard designers should treat key pins like NC (No
	Connect) pins. A socket designer has the option of creating a
	top mold piece that allows PGA key pins only where designated.
	However, sockets that populate all 16 key pins must be allowed,
	so the motherboard must always provide for pins at all key pin
	locations.
	See “NC Pins“ for more information.
NC Pins	The motherboard should provide a plated hole for an NC pin.
	The pin hole should not be electrically connected to anything.
NMI Pin	NMI is an input from the system that causes a non-maskable
	interrupt.
PGA Orientation Pins	No pin is present at pin locations A1 and AN1. Motherboard
	designers should not allow for a PGA socket pin at these
	locations.
	For more information, see the AMD Athlon™ Processor-Based
	Motherboard Design Guide, order# 24363.
PLL Bypass and Test	PLLTEST#, PLLBYPASS#, PLLMON1, PLLMON2,
Pins	PLLBYPASSCLK, and PLLBYPASSCLK# are the PLL bypass
	and test interface. This interface is tied disabled on the
	motherboard. All six pin signals are routed to the debug
	connector. All four processor inputs (PLLTEST#, PLLBYPASS#,
	PLLMON1, and PLLMON2) are tied to VCC_CORE with pullup
	resistors.
