7.10.2 Addressing Mode Select (A3)
The Addressing Mode can be one of two modes; Interleave mode or Sequential Mode, When the
A3 bit is “0”, Sequential mode is selected. When the A3 bit is “1”, Interleave mode is selected. Both
addressing Mode support burst length 2, 4 and 8 words.

Addressing Sequence of Sequential Mode
A column access is performed by incrementing the column address input to the device. The
address is varied by the Burst Length as the following.
