Pin functions
An external capacitor to ground fixes the half-bridge switching frequency with a
± 3 % precision.
Voltage reference capable of sourcing up to 240 µA. The current sunk from this
pin fixes the switching frequency of the half-bridge for each operating state.

Preheating: low impedance to set high switching frequency
Ignition and run mode: high impedance with controlled current sink in case of
HBCS threshold triggering.
