3. Burst Length (BL)
Burst Length (BL) is the number of word to be read or write as the result of a single READ or WRITE command.
It can be set on 2, 4, 8, 16 words boundary through Mode Register. The burst type is sequential that is incremental
decoding scheme within a boundary address to be determined by burst length. Device internal address counter
assigns +1 to the previous address until reaching the end of boundary address and then wrap round to least
significant address ( = 0).
