9.3
9.3.1
In the architecture, this LSI has 32-bit address spaces.
As listed in tables 9.2 to 9.15, this LSI can connect nine areas to each type of memory, and it
outputs chip select signals (CS0 to CS8) for each of them. CS0 is asserted during area 0 access. In
access to SDRAM connected to areas 2 and 3, signals such as RASx, CASx, RD/WR, and
DQMxx will be asserted. Furthermore, when the PCMCIA interface is selected in areas 5 and 6,
CE1A, CE1B, CE2A, and CE2B as well as CS5 and CS6 are asserted, according to the bytes to be
accessed.
9.3.2
The external address space has a capacity of 1.5 Gbytes and is used by dividing into 9 spaces. The
memory to be connected and the data bus width are specified in each space. The address map for
the entire address space is listed in tables 9.2 to 9.15.
