Data Pattern
Contains a pattern editor for entering data patterns in binary or hexadecimal
format. A pattern editor is a utility that allows you to search for a data
pattern.
Searching for Bit Patterns
You search for a bit pattern by using the box labeled Bitmask. Enter one of
the three following values:
• X = 'Don't care,'
• 0 = 'Match a 0',
• 1 = 'Match a 1.'
Example -- xxxxxx01 means 'Look for a data pattern where the first 6 bits
can be any value but the last two bits must be 01.'
Searching for Long Patterns
You can search for long pattern sequences by entering patterns into multiple
rows within the editor. Entering a pattern on one row and skipping several
rows before entering the second pattern tells Merlin to search for the entire
pattern between the two specified rows.
Example - Enter xxxxxx01 in row 1 and 11xxxxxx in row 2. This pattern
means 'Look for the pattern xxxxxx0111xxxxxx.'
