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

ZN and ZP Pins	ZN (AC5) and ZP (AE5) are the push-pull compensation circuit
	pins. In Push-Pull mode (selected by the SIP parameter
	SysPushPull asserted), ZN is tied to VCC_CORE with a resistor
	that has a resistance matching the impedance Z0 of the
	transmission line. ZP is tied to VSS with a resistor that has a
	resistance matching the impedance Z0 of the transmission line.
