However, 50ms is quite long time to sleep, and with some
configurations the SYNC_LOST may never happen, so the sleep can
be disabled here.

+ help
+ There is a 20ms sleep after VENC reset which seemed to fix the
+ reset. The reason for the bug is unclear, and it's also unclear
+ on what platforms this happens.
+
+ This option enables the sleep, and is enabled by default. You can
+ disable the sleep if it doesn't cause problems on your platform.
