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
μ
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.
