9.2
The pin configuration of the BSC is listed in table 9.1.
Table 9.1
9.3
9.3.1
In the architecture, this LSI has 32-bit address spaces.
As listed in tables 9.2 to 9.4, this LSI can connect two areas to each type of memory, and it
outputs chip select signals (CS0 and CS1) for each of them. CS0 is asserted during area 0 access.
9.3.2
The external address space has a capacity of 2 Mbytes and is used by dividing into two 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 9.4.
