2.8.3 Built in Customer Test Mode (Clock Acceleration)
The built in customer test mode, supported by this IC, saves testing time for customers in terms of
ballast end test. In that mode, the IC accelerates the internal clock in order to reduce the time of the 4
different procedures by the following factors (see Table 1).

In order to start the IC with an accelerated clock, set the voltage at the RES pin to GND (V
