Resume the target at its current code position,
or the optional @var{address} if it is provided.
-OpenOCD will wait 5 seconds for the target to resume.

@deffn {Command} {step} [address]
limit the address range.

+Data will be stored to specified destination. Available destinations are:
+@itemize @bullet
+@item @code{file://<outfile>} - Save trace logs into file.
+@item @code{tcp://<host>:<port>} - Send trace logs to tcp port on specified host. OpenOCD will act as a tcp client.

+Other parameters will be same for each destination.
+@itemize @bullet
+@item @code{poll_period} - trace data polling period in ms.
+@item @code{trace_size} - maximum trace data size.
+Tracing will be stopped automatically when that amount is reached.
+Use "-1" to disable the limitation.
+@item @code{stop_tmo} - Data reception timeout in ms.
+Tracing will be stopped automatically when no data is received within that period.
+@item @code{wait4halt} - if non-zero then wait for target to be halted before tracing start.
