1. This mode is available only on UFBGA176 and WLCSP64+2 packages.

2. In regulator bypass mode, PA0 is used as power-on reset. The connection between PA0 and NRST can consequently

prevent debug connection. If the debug connection under reset or pre-reset is required, the user must manage the reset

and the power-on reset separately.
