+@section Preparing a Target before Flash Programming
+
+The target device should be in well defined state before the flash programming
+begins.
+
+@emph{Always issue} @command{reset init} before @ref{flashprogrammingcommands,,Flash Programming Commands}.
+Do not issue another @command{reset} or @command{reset halt} or @command{resume}
+until the programming session is finished.
+
+If you use @ref{programmingusinggdb,,Programming using GDB},
+the target is prepared automatically in the event gdb-flash-erase-start
+
+The jimtcl script @command{program} calls @command{reset init} explicitly.

+Reads an option byte register from the stm32h7x device.
+The @var{num} parameter is a value shown by @command{flash banks}, @var{reg_offset}

+# read WPSN_CUR1R
