Note: Although nominally 1.25V is used even as name in the schematic the
output of the voltage regulator IC19 is slightly increased to 1.28V (see
Chapter 11 'Schematic'). With this sufficient high voltage is applied, even in
case of any possible voltage drops.

• The voltage supplied to the device pin W3 (marked "Ball_W3") must be
configured to either LVDVCC or E0VCC according to the device pinout.
Please check the device HW user's documentation for more details.
For more details, please refer to Chapter 11 'Schematic'. For typical
configuration of the jumpers, please refer to Chapter 8 'Jumper Configuration'.
