2.5

Interrupts and IDSEL

The add-in card interrupts are routed directly to the PCI system host. The Tsi340 is not involved with 
interrupt routing. The connection of the interrupt lines from the PCI connectors to the finger connector 
is arranged so that Int A of each PCI connector is routed to a different interrupt on the finger connector. 
Add-in card are numbered using AD[24:27] lines. 

Table 4

 maps the interrupt connections designation 

and AD line connections.

Table 5

 shows the IDSEL assignments.

2.6

Resets

Tsi340 is reset from the system host reset signal (from the finger connector). The secondary side reset 
is driven by Tsi340. There is no manual reset on the board.
