Preliminary Information
8.4 Frequency Identification (FID[3:0])
Table 11 shows the FID[3:0] DC characteristics. For more
information, see “FID[3:0] Pins” on page 74.
8.5 VCCA AC and DC Characteristics
Table 12 shows the AC and DC characteristics for VCCA. For more information, see
“VCCA Pin” on page 77
8.6 Decoupling
See the AMD Athlon™ Processor-Based Motherboard Design
Guide, order# 24363, or contact your local AMD office for
information about the decoupling required on the motherboard
for use with the AMD Athlon XP processor model 10.
