Bus Cycle Timing 5-159
18524C/0—Nov1996 AMD-K5 Processor Technical Reference Manual
AHOLD-Initiated
Inquire Hit to Shared
or Exclusive Line
Figure 5-10 shows an example similar to Figure 5-9, minus the
address parity error, but this inquire cycle hits either a shared
or exclusive line in the cache, as indicated by the assertion of
HIT and the negation of HITM two clocks after the assertion of
EADS. The processor invalidates the cache line because sys-
tem logic asserts INV with EADS. The processor may drive a
new bus cycle as early as one clock after system logic negates
AHOLD.
