*Note :
1. BRSW modes is enabled by setting A
At the BRSW Mode, the burst length at write is fixed to "1" regaredless of programmed burst length.
2. When BRSW write command with auto precharge is executed, keep it in mind that t
Auto precharge is executed at the burst-end cycle, so in the case of BRSW write command,
the next cycle starts the precharge.
