bits in the sequence shown as the following.
Addressing sequence of Sequential mode (A3)
address input to the device.
Addressing sequence of Interleave mode
(R-3) CAS Latency field (A6 to A4)
(R-4) Test Mode field (A7)
(R-5) Reserved field in the Regular Mode Register
CAS Latency = 4
Command
A column access is started from the inputted lower address and is performed by interleaving the address
A column access is started from the inputted lower address and is performed by incrementing the lower

RDA command to the first data read. The minimum values of CAS Latency depends on the frequency
of CLK. In a write mode, the place of clock that should input write data is CAS Latency cycles − 1.

DQ
This field specifies the number of clock cycles from the assertion of the LAL command following the
This bit is used to enter Test Mode for supplier only and must be set to “0” for normal operation.
Reserved bits (A8 to A13, BA2)
These bits are reserved for future operations. They must be set to “0” for normal operation.
