Q_

Output

Synchronous Data Outputs: Output data is synchronized to the respective C and C# or to K

and K# rising edges if C and C# are tied HIGH. This bus operates in response to R# commands.

See Ball Assignment figures for ball site location of individual signals. The x8 device uses D0-

D7. The x9 device uses D0-D8. The x18 device uses Q0–Q17. Remaining signals are NC. The x36

device uses Q0–Q35. Remaining signals are NC.
