PKA_SR register
| BUSY | PKA operation is in progress This bit is set to ‘1’ whenever START bit in the PKA_CR is set. It is automatically cleared when the computation is complete, meaning that PKA RAM can be safely accessed and a new operation can be started. 0: No operation is in progress (default) 1: An operation is in progress Nota: if PKA is started with a wrong opcode the IP will be busy for a couple of cycles then it will abort automatically the operation and go back to ready (BUSY bit is set to ‘0’). |
| PROCENDF | PKA End of Operation flag 0: Operation in progress 1: PKA operation is completed. This flag is set when the BUSY bit is de-asserted. |
| RAMERRF | PKA RAM error flag 0: No PKA RAM access error 1: An AHB access to the PKA RAM occured while the PKA core was computing and using its internal RAM (AHB PKA_RAM access are not allowed while PKA operation is in progress). |
| ADDRERRF | Address error flag 0: No Address error 1: Address access is out of range (unmapped address) |
| FAULTFSMF | Fault fsm error flag 0: No fault has been detected 1: A fault on fsm has been detected |
| FAULTERRORCODEF | Fault error code error flag 0: No fault has been detected 1: A fault has altered the execution of the operation and the internal fault check has been skipped |
