This anomaly applies to Revision 3, build codes QFAA-Gx0, QFAB-Gx0, CIAA-Gx0.
It was inherited from the previous IC revision
Revision 2.
Symptoms
False END events.
Conditions
Offset calibration is run with TACQ < 10 µs before sampling is started.
Consequences
The END event can occur earlier than expected. Data is not ready.
Workaround
Apply one of the following workarounds:
- Run offset calibration with TACQ >=10 µs.
- Apply STOP task after calibration, before sampling. CALIBRATEOFFSET -> CALIBRATEDONE -> STOP -> STOPPED -> START.
