Notes
78. BM, SIZE, and BE must be reconfigured 1 cycle before operation is guaranteed. BM, SIZE, and BE should remain static for any particular port configuration.
79. In x36 mode, BE input is a “Don’t Care.”
80. DQ represents data output of the chip.
81. x18 and x9 configuration apply to right port only.
