13. External Bus Interface
The external bus interface controls the interface between the device and the external memory and also the
external I/O, and has the following features.
25-bit (32 Mbytes) address output
6 independent banks owing to the chip select function.
Can be set to anywhere on the logical address space for minimum unit 64 Kbytes.
Total 32 Mbytes
× 6 area setting is available by the address pin and the chip select pin.
8/16-bit bus width setting are available for every chip select area.
Areas 6 and 7 allow the inclusive areas to be set.
Programmable automatic memory wait (max. for 7 cycles) can be inserted.
DRAM interface support
Three kinds of DRAM interface: Double CAS DRAM (normally DRAM I/F)
Single CAS DRAM
Hyper DRAM
2 banks independent control (RAS, CAS, etc. control signals)
DRAM select is available from 2CAS/1WE and 1CAS/2WE.
Hi-speed page mode supported
CBR/self refresh supported
Programmable wave form
Unused address/data pin can be used for I/O port.
Little endian mode supported
Clock doubler: Internal bus 50 MHz, external bus 25 MHz
