Note:
When entering the data pattern in the “data” section of this screen, if you are reading the data
pattern from a recorded trace, you must reverse the order of the bytes listed for each DWORD
entered. For example, if you want to capture (or exclude) “00 01 02 03” (as displayed in the
trace), you must enter this pattern as “03 02 01 00”.
