The power management features of the processor are compliant with the ACPI 1.0b and ACPI 2.0 specifications. 4.1 Power Management States The AMD Athlon XP processor model 10 supports low-power Halt and Stop Grant states.
Preliminary Information AMD Athlon™ XP Processor Model 10 Data Sheet 26237C—May 2003 The following sections provide an overview of the power m a n a g e m e n t s t a t e s . Fo r m o re d e t a i l s , re f e r t o t h e AMD Athlon™ and AMD Duron™ System Bus Specification, order# 21902. Note: In all power management states that the processor is powered, the system must not stop the system clock (SYSCLK/SYSCLK#) to the processor.
Preliminary Information 26237C—May 2003 AMD Athlon™ XP Processor Model 10 Data Sheet must first connect the system bus. Connecting the system bus places the processor into the higher power probe state. After the Northbridge has completed all probes of the processor, the Northbridge must disconnect the AMD Athlon system bus again so that the processor can return to the low-power state.
Preliminary Information AMD Athlon™ XP Processor Model 10 Data Sheet 26237C—May 2003 In C2, probes are allowed, as shown in Figure 3 on page 9 The Stop Grant state is also entered for the S1, Powered On Suspend, system sleep state based on a write to the SLP_TYP and SLP_EN fields in the ACPI-defined Power Management 1 control register in the Southbridge. During the S1 Sleep state, system software ensures no bus master or probe activity occurs.
Preliminary Information 26237C—May 2003 AMD Athlon™ XP Processor Model 10 Data Sheet The Northbridge contains BIOS programmable registers to enable the system bus disconnect in response to Halt and Stop Grant special cycles. When the Northbridge receives the Halt or Stop Grant special cycle from the processor and, if there are no outstanding probes or data movements, the Northbridge deasserts CONNECT a minimum of eight SYSCLK periods after the last command sent to the processor.

Preliminary Information AMD Athlon™ XP Processor Model 10 Data Sheet 26237C—May 2003 9 Signal and Power-Up Requirements The AMD Athlon™ XP processor model 10 is designed to provide functional operation if the voltage and temperature parameters are within the limits of normal operating ranges. 9.1 Power-Up Requirements Signal Sequence and Timing Description Figure 13 shows the relationship between key signals in the system during a power-up sequence.
Preliminary Information AMD Athlon™ XP Processor Model 10 Data Sheet 26237C—May 2003 Power-Up Timing Requirements. The signal timing requirements are as follows: 1.
