[71] CLOCK: RCOSC calibration

This anomaly applies to IC Rev. Engineering B, build codes QFAA-BA0, CHAA-AA0.

It was inherited from the previous IC revision Engineering A.

Symptoms

RCOSC only calibrates on every second calibration request.

Conditions

Always

Consequences

RCOSC not properly calibrated.

Workaround

Trigger TASKS_CAL, wait for EVENTS_DONE. Trigger TASKS_CAL again, wait for EVENTS_DONE each time the RCOSC is to be calibrated.
