Native Interface

Auto-precharge with a read or write can be used within the Native interface. This is one of the five instructions implemented by the MCB: read, write, refresh, auto precharge with a read, and auto precharge with a write.

For more information, refer to the"MCB Operation" -> "Instructions" section of the Spartan-6 FPGA Memory Controller User Guide(UG388):

AXI Interface

You can enable Auto-Precharge On Each Transactionwithin the AXIParameter Options Screen of the MIG interface; when checked, all MCB read/write transactions on that port close the bank/page to be closed (with auto-precharge) after the transaction completes.
