Write operation:
Burst write or single write mode is selected by the OPCODE (BA1, BA0, A12, A11, A10,
A9, A8) of the mode register.
1. Burst write:
A burst write operation is enabled by setting OPCODE (A9, A8) to (0, 0). A burst write
starts in the same clock as a write command set. (The latency of data input is 0 clock.) The burst length can
be set to 1, 2, 4 and 8, like burst read operations. The write start address is specified by the column address
and the bank select address (BA0/BA1) at the write command set cycle.

2. Single write:
A single write operation is enabled by setting OPCODE (A9, A8) to (1, 0). In a single write
operation, data is only written to the column address and the bank select address (BA0/BA1) specified by the
write command set cycle without regard to the burst length setting. (The latency of data input is 0 clock).
