data contained in the three address registers (TA1, TA2,
E/S, in that order).
If the pattern matches, the AA
(Authorization Accepted) flag will be set and the copy
will begin. A pattern of alternating 1s and 0s will be
transmitted after the data has been copied until a reset
pulse is issued by the master. Any attempt to reset the
part will be ignored while the copy is in progress. Copy
typically takes 30
s. The data to be copied is deter-
mined by the three address registers. The scratchpad
data from the beginning offset through the ending offset,
will be copied to memory, starting at the target address.
Anywhere from 1 to 32 bytes may be copied to memory
with this command. The AA flag will be cleared only by
executing a write scratchpad command.
