2.When BRSW write command with auto precharge is executed, keep it in mind that t
At the BRSW Mode, the burst length at write is fixed to “1” regardless of programmed burst length.
Auto precharge is executed at the next cycle of burst-end, so in the case of BRSW write command, the precharge
command will be issued after two clock cycles.
