This anomaly applies to Revision 1, build code PAAA-B00.
It was inherited from the previous SoC revision Engineering B.
Symptoms
The device behaves erratically or becomes unresponsive.
Conditions
The XOSTART task is triggered when the PLLSTART task is not triggered and CPU is sleeping.
Consequences
Peripherals outside the MCU domain can behave erratically.
Workaround
Trigger TASKS_PLLSTART before TASKS_XOSTART is triggered and trigger TASKS_PLLSTOP after TASKS_XOSTOP is triggered. Current consumption might increase depending on the use case.
