The sequence has 16 slots and each slot a duration of min tslot = ~64 µs. Each slot contains two steps. First a single automatic measure initiated by the SOC and configured by register settings is performed, second a single (if min tslot = ~64 µs) or multiple (min tslot > 64 µs) internal measure for on-chip functions and decisions might be performed. Whenever there is no automatic or internal measurement, manual measure initiated by the SOC can be performed. If no measurement is performed, the ADC is turning off to reduce power consumption. The sequencing is configured in such a way that it fulfills the Intel ADC specification and performs automatically measurement at the appropriate time (platform state defendant) Manual Measurements 15.3.1 An automatic measurement can be assigned to a specific slot while a manual measurement can’t. Manual measurements will be performed at free slots or whenever there is space in the internal measure frame. Free slots are unassigned slots, slot with down sampling while not measuring and masked or disabled slots in standby mode. To initiate a manual measurement two separate registers MANCONV0 and MANCONV1 exists, one bit for each ADC Channel. One or more channels can be selected in one register write.
