Bit 4—2-CAS Method/2-WE Method Select (CW2): Selects whether the 2-CAS method or 2-
WE method is used for byte access when areas 2 to 5 are designated as 16-bit DRAM space.
Bits 3 and 2—Multiplex Shift Count 1 and 0 (MXC1, MXC0): These bits select the size of the
shift to the lower half of the row address in row address/column address multiplexing for the
DRAM interface. In burst operation on the DRAM/PSRAM interface, these bits also select the
row address to be used for comparison.
