Address Multiplexing: Synchronous DRAM can be connected without external multiplexing
circuitry in accordance with the address multiplex specification bits AMX1 and AMX0 in MCR.
Table 10.13 shows the relationship between the address multiplex specification bits and the bits
output at the address pins.
A25–A16 and A0 are not multiplexed; the original values are always output at these pins.
When A0, the LSB of the synchronous DRAM address, is connected to the SH7708 Series, it
performs longword address specification. Connection should therefore be made in this order:
connect pin A0 of the synchronous DRAM to pin A2 of the SH7708 Series, then connect pin A1
to pin A3. Table 10.14 shows the example of correspondence between SH7708 Series and
synchronous DRAM address pins.
