[79] NFCT: A false EVENTS_FIELDDETECTED event occurs after the field is lost

This anomaly applies to IC Rev. Rev 1, build codes QFAA-B00, QFAB-B00, CIAA-B00.

It was inherited from the previous IC revision Engineering C.


A false EVENTS_FIELDDETECTED event occurs.


The task TASK_SENSE is triggered within 150 µs of the event EVENTS_FIELDLOST.


EVENTS_FIELDDETECTED will occur after a field is lost. (SHORT between eventfieldlost and taskSense should not be used since a false fieldDetected event will occur from using the task.)


Wait 150 µs after an EVENTS_FIELDLOST event before triggering TASK_SENSE.
