A Global MCP (BLKMD = 11 and BLKAD = 10XX), takes the same amount of time as the single, dual, and quad block MCP. In addition to requiring a no-op row cycle to initiate a global MCP, a row cycle (either no-op or data loading) is also required to complete the operation. If the customer interface is monitoring RST_ACTIVE to determine when to send a subsequent row cycle, it will never see RST_ACTIVE transition low. One method of operation would be to continue sending no-op row cycles until RST_ACTIVE goes low then continue loading data with real row cycles. Another method of operation is to delay greater than 10 μs, then start loading new data to DMD.
