-To perform flashing operations:
+<p style="text-align: justify;">You can program the multifunctional push button on the Portenta Hat Carrier for diverse implementations with a single press or initiate specific events, switch between states, and execute actions as required by the application.</p>
 
-1. Do a long press on the PB1 push button and release it.
-2. To exit from the flashing mode and restart the system with the changes made, do a single press on the PB1 push button.
