Instruction Set (Continued)
9.2.1.3
CPUID Instruction with EAX = 00000002h
Standard function 02h (EAX = 02h) of the CPUID instruc-
tion returns information that is specific to the National
Semiconductor family of processors. Information about
the TLB is returned in EAX as shown in Table 9-20. Infor-
mation about the L1 cache is returned in EDX.
