Enabling the tamper protection bit disables test mode in Stratix IV devices. This
process is irreversible and prevents Altera from conducting carry-out failure analysis
if test mode is disabled. Contact Altera Technical Support to enable the tamper
protection bit.
No Key Operation
Only unencrypted configuration bitstreams are allowed to configure the device.
