This feature gives the customer the flexibility to align the preheating frequency to the filament power in the
preheating phase.
an 8.2 kΩ resistor at the RTPH pin 11. To force the IC to remain in preheating, the voltage level at the RTPH pin 11
has to be set to 5.0 V. The duration of this 5.0 V signal defines the time of the preheating (see I
