Security Validation

• If the region is configured as secure, then only the secure request can access this region.
• If the region is configured as secure, then the read and write permissions are independently checked to determine whether or not the transactions are allowed.
• If the transaction is non-secure and the region is configured as secure, then the check fails, and the transaction generates a system error.
• If the region is configured as non-secure and the transaction is non-secure, then read and write permissions are independently checked to determine whether or not the transaction is allowed. If the check fails, the transaction is handled by the error handler.
