BV - Block of Memory Verify
3-23
3
If the upper address of the range is not on the correct boundary for
an integer multiple of the data to be verified, data is verified to the
last boundary before the upper address. No address outside of the
specified range is read from in any case. The Effective address
messages displayed by the command show exactly the extent of the
area read from.
Examples
Example 1: For this example, assume memory from $20000 to
$2002F is as indicated. In this example the default data element size
is word, and the block verify was successful (i.e., nothing printed).
