+SWIM
+-------------------------------------------------------------------------------
+
+This is a capture of an ST-Link V2 programming an STM8 using the SWIM protocol.

+----------
+
+Using stm8flash with an ST-Link V2 adapter to program an STM8S003F3.
+
+Command line:
+
+  $ stm8flash -c stlinkv2 -p stm8s003f3 -s flash -w prog.ihx
+
+stm8flash is modified both for correctness and to generate the test sequences.
+The updated version can be found at https://github.com/mjagdis/stm8flash.
+
+A complete flash programming operation. SWIM is enabled and set to high
+speed mode (notice how the pulse width and period decreases after the
+initial chatter). A read of the affected memory region is made, compared to
+the data to be written and those blocks that contain differences are written
+back. Finally an SRST SWIM command is sent to terminate the conversation
+and reset the target.
