| 11. | The width of the address bus determines the amount of memory a system can address.
|
| 12. | The backplane served as the address bus and the ribbon cable as the data bus.
|
| 13. | Earlier models of DVK series were based on K1801VM1 or K1801VM2 microprocessors with 16 bit address bus.
|
| 14. | ARM9 cores have separate data and address bus signals, which chip designers use in various ways.
|
| 15. | The address bus was always active so the VMA ( valid-memory address ) output was eliminated.
|
| 16. | The 6502 is a little-endian 8-bit processor with a 16-bit address bus.
|
| 17. | In the later models, the KM1801VM3 microprocessor ( with 22 bit extended address bus ) was used.
|
| 18. | This was done in response to community requests to address buses that were double parking during their recovery times.
|
| 19. | This was a 68000 with an 8-bit data bus and a smaller ( 20 bit ) address bus.
|
| 20. | During refresh the contents of the Interrupt register I are sent out on the upper half of the address bus.
