11.10 LIN COMMUNICATIONS
11.10.1 Introduction
The PICkit Serial Analyzer LIN support is confined to master and monitor functionality.
As a master, the PICkit Serial Analyzer accepts instruction from the host in the form of
script tag(s). Execution of the script results in the PICkit Serial Analyzer transmitting on
the LIN bus as a master. In practice, the transmission would constitute a LIN frame
header or an entire LIN frame (i.e., message).
As a LIN bus monitor, the PICkit Serial Analyzer can detect and report all events/trans-
actions on the bus generated by other devices on the bus or generated by the PICkit
Serial Analyzer master module. The ‘event marker’ tag(s) are used to report bus activity
in its variety of forms but must be enabled, individually, using CONTROL_BLOCK
Configuration bits as seen below.
