As shown in figure 9.16, two sets of SDRAMs of 32 Mbytes or smaller can be connected to the

same CS space by using RASU, RASL, CASU, and CASL. In this case, a total of 8 banks are

assigned to the same CS space: 4 banks specified by RASL and CASL, and 4 banks specified by

RASU and CASU. When accessing the address with A25 = 0, RASL and CASL are asserted.

When accessing the address with A25 = 1, RASU and CASU are asserted.
