status register after a SPI read command.
Over-current Fault
protect each output structure against resistive short-circuit
condition. This protection is composed by eight predefined
current levels (time dependent) to fit Xenon-HID manners by
default or, 55 W or 28 W bulb profiles, selectable separately
by Xenon bit and 28 W bits (as illustrated
37).
