| Property: | - |
Devices where the EIC is configured
as Mix-Secure, read and write accesses 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 Enabled-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.
