VID[4:0] (Voltage Identification)
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-III+ processor. For more information about
these signals, see the Embedded AMD-K6™ Processors BIOS
Design Guide Application Note, order# 23913.
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.
