In this case, the memory access is always requested by the scanner. The memory access request is granted to the scanner if no other higher priority source is requesting access. The memory access cycles will not be granted to lower priority sources than the scanner until it completes operation i.e., SGO = 0.
Important: If TRIGEN = 1 and BURSTMD = 1, the user need to ensure that the trigger source is active for the Scanner operation to complete.
