7.10.2.1. Addressing Sequence of Sequential Mode
7.10.2.2. Addressing Sequence for Interleave 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.
A Column access is started from the inputted column address and is performed by interleaving the
address bits in the sequence shown as the following.
