Bit 4—2-CAS Method Select (CW2): Write 1 to this bit when areas 2 to 5 are designated as 8-bit
DRAM space, and 0 otherwise.
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 interface, these bits also select the row address
to be used for comparison.
