3.8.2 Failures

If a failure (e.g., PUF SRAM access error) is detected, either during Initialization, Zeroization or other operations, the PUF module enters the Locked state. When the PUF module is in Locked state, no operations other than Zeroize can be performed. The software must determine if a Zeroize operation or if a repower of the PUF or the product is required.
