2.8.3
The built-in customer test mode, supported by this IC, saves testing time for customers in terms of ballast end test.
In this mode, the IC accelerates the internal clock in order to reduce the time of the 4 different procedures by the
following factors (see

2.8.3.1
The clock acceleration (Built-in Customer Test Mode) is activated when the chip supply voltage exceeds V
> 14.0 V and the voltages at the run and preheating frequency pins are set to V
