Note: Discrete interrupt selection allows each port to be treated as a distinct component. Therefore, ports may be assigned separate or shared IRQs. |

MISCELLANEOUS TECHNICAL NOTES |
|
When cascading boards; use IRQ3, 4, or 5, as a shared interrupt on the primary board. Set the consecutive boards using JP5, and JP6 only. Connect a wire from CN7(location unidentified) on the first board to CN4 on the consecutive boards. |
