block programs the SDRAM’s mode register. Thus, the address of the access should be programmed
to place the correct mode information on the SDRAM address pins. Because the SDRAM does not
register this information, it doesn’t matter if the IMRS access is a read or a write or what, if any, data is
put onto the data bus. The DRAM controller clears IMRS after the
