[101] CLOCK: Sleep current increases after soft reset

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.

Symptoms

Sleep current with LFXO active is 0.5 µA higher than expected.

Conditions

Low frequency crystal oscillator is active, due to use of RTC or WDT, and a soft-reset is issued or a CPU lock-up reset occurs.

Consequences

Increased sleep current.

Workaround

None.
