Section 13 Bus State Controller (BSC)
13.1.4
The BSC has the 11 registers shown in table 13.2. In addition, the synchronous DRAM mode
register incorporated in synchronous DRAM can also be accessed as this LSI's register. The
functions of these registers include control of interfaces to various types of memory, wait states,
and refreshing.
