11.5 COMM
The Comm module will decode Tag bytes from the data stream in the script buffer. The
Tag bytes may represent commands to internally configure the PICkit™ Serial Ana-
lyzer and report status, or the Tag bytes may be protocol specific identification that
needs to be translated into the device under test’s protocol and communicated to the
device. The Comm module performs both of these functions. This section will describe
the Comm Tags common to all supported serial protocols. Table 11-11 describes the
Tags (CCMD) used in the data stream to the Comm controller. Table 11-12 describes
Tags (CDATA) used in the data stream from the Comm controller.
