Notes: 1. BSIZE represents the BSIZE bit in the SDCmCNT control register.
2. DSZ represents the DSZ bit in the SDRAMm address register.
3. DDBW represents the DDBW bit in the SDRAMm address register.
4. ba[1:0] and ma[12:0] represent, respectively, the SDRAM bank address and SDRAM
address.
5. When the RD, WR or PRA command is issued, this carries the pre-charge option
signal.
