7.5.11 Burst Terminate of Read
The BURST TERMINATE command is used to truncate read bursts (with Auto Pre-charge disabled). The most
recently registered READ command prior to the BURST TERMINATE command will be truncated. Note that the
BURST TERMINATE command is not bank specific.
This command should not be used to terminate write bursts.

7.6 Write
The WRITE command is used to initiate a burst write access to an active row, with a burst length as set in the Mode
Register. BA0 and BA1 select the bank, and the address inputs select the starting column location. The value of A10
determines whether or not Auto Pre-charge is used. If Auto Pre-charge is selected, the row being accessed will be
pre-charged at the end of the write burst; if Auto Pre-charge is not selected, the row will remain open for subsequent
accesses.
