[81] GPIO: PIN_CNF is not retained when in debug interface mode

This anomaly applies to IC Rev. Rev 1, build codes QIAA-Cx0, CKAA-Cx0.

It was inherited from the previous IC revision Engineering C nRF52840.


GPIO pin configuration is reset on wakeup from System OFF.


The system is in debug interface mode.


GPIO state unreliable until PIN_CNF is reconfigured.
