Detailed Description

Examine input for specified access code, one bit at a time.

input: stream of bits, 1 bit per input byte (data in LSB) output: unaltered stream of bits (plus tags)

This block annotates the input stream with tags. The tags have key name [tag_name], specified in the constructor. Used for searching an input data stream for preambles, etc.
