[97] GPIOTE: High current consumption in System ON Idle mode

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

High current consumption (<20 µA) in System ON Idle mode

Conditions

GPIOTE used with one or more channels in input mode.

Consequences

Higher current consumption

Workaround

Use Port event to detect transitions on inputs instead of GPIOTE input mode.
