The following procedure is required to get OTFA operational for cryptographic functionality.
After a reset event, the follow procedure is required.
The SW can make adjustments to the OTFA configuration when it is enabled if it follows a strict protocol.
The OTFA scheduler does not support on the fly adjustments. Software will need to insure that these adjustments have no impact on current operations and near future operations by following the defined procedure.
Stop all transactions by external methods
MAC_ERR[N] will get set when a MAC compare error event occurs for region [N] during a read operation.
WRITE_ERR[N] will get when write transaction occurs when write_protection is set for region [N].
REGION_BV[N] will get set by one of the 3 possible source events.
CTR_WKV[N] will get set when OCP Write transaction violates the AES CTR mode write rule.
