DPWM Oscillator Resistor Adjust. A resistor to ground on this lead sets the frequency of the DPWM
oscillator. This lead can optionally accept a 22.5Hz to 440Hz clock that will become the source timing of
the internal DPWM signal.

Low-Supply Voltage Monitor Input. Used to monitor the inverter voltage for undervoltage conditions.
High-Supply Voltage Monitor Input. Used to monitor the inverter voltage for overvoltage conditions.
Power-Supply Connections. Both pins must be connected.
No Connection. Do not connect any signal to this pin.
Lamp Frequency Step Input. This active-high digital input moves the lamp oscillator frequency up or
down by 1%, 2%, 3%, or 4% as configured in the EMIC register. This pin is logically ORed with
the STEPE bit in the EMIC register.
Ground Connection
Lamp Current Overdrive Enable Input. A high digital level at this input enables the lamp current
overdrive circuit. The amount of overdrive current is configured by the LCOC register. When this input is
low, the lamp current is set to its nominal level. This pin is logically ORed with the LCOE bit in the LCOC
register.
Lamp On/Off Control Input. A low digital level at this input turns the lamp on. A high digital level turns the
lamps off, clears the fault logic, and places the device into the power-down mode. The high-to-low
transition on this input issues a controller reset, which clears the fault logic and reinitiates a lamp strike.
This pin is logically ORed with the PDNE bit in the CR2 register.
