OVERVIEW
Internally, the PICkit? Serial Analyzer operates two firmware state controllers running
in parallel – EXEC (executive) and COMM (communication). The EXEC controller is
responsible for overall PICkit? Serial Analyzer configuration, moving data to/from the
host (via USB) and moving data to/from the COMM controller (via RAM buffers). The
COMM controller supervises serial communication with the target device. This includes
both configuring the necessary communication hardware and executing a sequential
‘script’ defining a serial ‘transaction’.

Data streams associated with PICkit? Serial Analyzer are formatted with markers
called “TAG” bytes. A TAG may be stand-alone or accompanied by data. As seen in
Table 9-1, the data stream for each state controller has a set of associated TAG bytes
defined in detail later in the document.
