+ help
+ For some unknown reason we may get SYNC_LOST errors from the display
+ subsystem at initialization time if we don't sleep before resetting
+ the DSS. See the source (dss.c) for more comments.
+
+ However, 50ms is quite long time to sleep, and with some

+ be disabled here.

+ There is a 20ms sleep after VENC reset which seemed to fix the

+
+ This option enables the sleep, and is enabled by default. You can
+ disable the sleep if it doesn't cause problems on your platform.
