23542A/0-September 2000 Preliminary Information AMD-K6™-2E+ Embedded Processor Data Sheet 5.53 VID[4:0] (Voltage Identification) Pin Attribute Summary Output For AMD PowerNow! technology-enabled processors, the VID[4:0] signals are used to drive the VID inputs of the DC/DC regulator that generates the core voltage for the processor. The processor VID[4:0] outputs default to 01010b when RESET is sampled asserted. Note that these pins are supported on the low-power versions only of the AMD-K6-2+ processor. For more information about these signals, see the Embedded AMD-K6™ Processors BIOS Design Guide Application Note, order# 23913. Driven VID[4:0] are initialized to the default state after RESET is sampled asserted, the CPU input clock is running, and the core and I/O voltages are applied. Thereafter, the VID [4:0] outputs are always driven. Chapter 5 Signal Descriptions 137
