In addition, the snoop address on A31–A0 is again registered on the next CLK (not BCLK)
rising edge. For proper operation, the snoop addresses registered on these two separate
occasions must be consistent. Only normal and MOVE16 bus transfers can be snooped.
The MC68060 then examines the address of the transfer and invalidates the line in its
caches in which the address matches. This process is done quietly without external indica-
tion that a cache entry has been invalidated. Note that when snooping is enabled and an
entry matches in the MC68060 caches, the entry is invalidated regardless of the state of the
R/W signal, transfer size, or whether or not the line has clean or dirty data. If SNOOP is
negated, no snooping is done, and no lines in the caches are invalidated.
