Write operation:
Burst write or single write mode is selected by the OPCODE (A13, 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, 8, and full-page, like burst read operations. The write start address is specified by the column ad-
dress and the bank select address (BA) at the write command set cycle.
