Please note:
The 'programmer controlled – target power supply' has a tolerance of approximately +/- 5%, so
the generated voltage may not be the precise value of 3.0V, 3.3V, 4.7V or 5.0V specified in the
'Target voltage settings' in your project. It could be any voltage between the 'Min' and 'Max'
voltages show in the table.
