29.8.5 Event Control
Important: For SAM
L11 Non-Secure accesses, read and write accesses (RW*) are allowed only
if the external interrupt x (EXTINTx) is set as Non-Secure in the NONSEC register
(NONSEC.EXTINTx bit). Some restrictions apply for the Non-Secure accesses to an
Enable-Protected register as it will not be possible for the Non-Secure to configure it
once this register is enabled by the Secure application. This will require some veneers
to be implemented on Secure side.
