The bit n of USER enables the non-secure mode of USERn. The registers whose USER bit or bitfield n is set in non-secure mode by NONSECUSER.USERn are USERn registers.

These bits set the security attribution for the individual event users.

Value	Description
0	The corresponding event user is secured. When the module is PAC secured, the configuration and status bits for this event user are only available through the secure alias. Attempts to change the event user configuration through the non-secure alias will be silently ignored and reads will return 0.
1	The corresponding event user is non-secured. The configuration and status bits for this event user are available through the non-secure alias.
