This anomaly applies to Revision 1, build code PAAA-B00.
It was inherited from the previous SoC revision Engineering B.
Symptoms
EGU interrupt uses the same security setting as DPPI channel 0 regardless of how it is configured.
Conditions
EGU is used, and the DPPI channel 0 security setting is different from the EGU peripheral's security setting.
Consequences
All interrupt-related registers use the same security setting as DPPI channel 0.
Workaround
Set the security attribution of the EGU peripheral to the desired level and apply the same security attribution to DPPI channel 0.
