13.8 Scanning Modes

The interaction of the scanner with the system operation is controlled by the priority selection in the system arbiter (refer to the “Memory Access Scheme” section for more details). When using the scanner module in conjunction with the CRC module, the system arbiter needs to be configured such that the scanner has a higher priority than the CPU to ensure that a memory access request is granted when it occurs. Additionally, BURSTMD and TRIGEN bits also determine the operation of the scanner.
