Functional Description</h2>
|
||
|
|
|
||
|
|
<dl>
|
||
|
|
<dd> The copy command replicates a specified number of bytes from one place
|
||
|
|
in memory to another.</dd>
|
||
|
|
<p>If to is less than from, copying is performed in ascending order starting
|
||
|
|
at from. If from is less than to, copying is performed in descending order
|
||
|
|
starting at from + size.
|
||
|
|
<p>When moving a data block down, the source data is copied from the bottom
|
||
|
|
of the block upwards: and when moving a data block up, the source data is
|
||
|
|
copied from the top of the block downwards. By this technique, there is no
|
||
|
|
risk of copying over data in overlapping block move operations; as the data
|
||
|
|
in the overlapping area is copied first.

a base address of 0x80020000, to another 8-Kbyte area starting at the address
|

0x80060000.</li>
