Burst read and burst write:
Burst write is performed for the specified burst length starting from the column
address specified in the write cycle.
Burst read and single write:
Data is only written to the column address specified during the write cycle,
regardless of the burst length.
A7:
Keep this bit Low at the mode register set cycle. If this pin is high, the vender test mode is set.
A6, A5, A4: (LMODE):
These pins specify the CE latency.
A3: (BT):
A burst type is specified. When full-page burst is performed, only "sequential" can be selected.
A2, A1, A0: (BL):
These pins specify the burst length.
