Help¶

In streaming mode, TzCtrl is used to receive start/stop commands from
Tracealyzer and in some cases also to transmit the trace data (for stream
ports that uses the internal buffer, like TCP/IP). For such stream ports,
make sure the TzCtrl priority is high enough to ensure reliable periodic
execution and transfer of the data, but low enough to avoid disturbing any
time-sensitive functions.

In Snapshot mode, TzCtrl is only used for the stack usage monitoring and is
not created if stack monitoring is disabled. TRC_CFG_CTRL_TASK_PRIORITY should
be low, to avoid disturbing any time-sensitive tasks.
