word | 31:0 | roRead-only | 0x0 | PUF syndrome word generated by key registration. The syndrome word is ready when PUF_STATUS[WR] is set. Reading this register clears the PUF_STATUS[WR] bit. The CSU Secure Processor will continue to load syndrome words into this register until all syndrome data has been generated. The CHASH value is stored here also but is not valid until PUF_STATUS[KEY_RDY] is asserted. |
