The burst read/single write mode is entered by programming the write burst mode bit
(M9) in the mode register to a 1. In this mode, all WRITE commands result in the access
of a single column location (burst of one), regardless of the programmed burst length.
READ commands access columns according to the programmed burst length and se-
quence, just as in the normal mode of operation (M9 = 0).
