11. External Bus Interface
The external bus interface controls the interface between the external memory and the external I/O. Its features
are as follows :
24-bit (16 MB) address output
An 8/16-bit bus width can be set by chip select area.
Inserts an automatic and programmable memory wait (for seven cycles at maximum) .
Unused addresses/data pins are available as I/O ports.
Support for little endian mode
Use of a clock doubler, 32 MHz internal and 16 MHz external bus operations
