NOTES :
1. OP Code : Operand Code
2. MRS can be issued only at all banks precharge state.
3. Auto refresh functions are the same as CBR refresh of DRAM.
4. BA0 ~ BA1 : Bank select addresses.
5. During burst read or write with auto precharge, new read/write command can not be issued.
6. Burst stop command is valid at every burst length.
7. DQM sampled at the positive going edge of CLK masks the data-in at that same CLK in write operation (Write DQM latency
