Mode Register Configuration
The mode register is set by the input to the address pins (A0 to A13) during mode register set cycles. The
mode register consists of five sections, each of which is assigned to address pins.
A13, A12, A11, A10, A9 A8: (OPCODE):
The SDRAM module has two types of write modes. One is the
burst write mode, and the other is the single write mode. These bits specify write mode.
