29.8.11 Debouncer Enable
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.
