Section 9 Bus State Controller (BSC)
A port is used to generate the REG signal that switches between the common memory and
attribute memory. As shown in the example in figure 9.44, when the total memory space necessary
for the common memory and attribute memory is 32 Mbytes or less, pin A24 can be used as the
REG signal to allocate a 16-Mbyte common memory space and a 16-Mbyte attribute memory
space.
