Hi All,
The parts that refer to the BASEPRI_NS register being set on return from Secure services has been removed from the document (marked with strikethrough), as the attack surfaces introduced by not doing it are mitigated by the veneer stack checking on secure function entry.
Sorry for the inconvenience.
Best regards, Mate
