6.5.10
With DRAM, in addition to full access (normal access) in which data is accessed by outputting a
row address for each access, a fast page mode is also provided which can be used when making a
number of consecutive accesses to the same row address. This mode enables fast (burst) access of
data by simply changing the column address after the row address has been output. Burst access
can be selected by setting the BE bit in MCR to 1.
Burst Operation
(Address shift size set to 9 bits)
