All switches are set to ON at factory. It means that Picolo U4 H.264 PCI-104 is configured for module slot1:
- Uses IDSEL0 as a chip select during configuration read and write transactions
- Uses REQ0# / GNT0# lines for PCI bus arbitration
- Uses the INTA# line as interrupt line 0
- Uses CLK0 as PCI bus clock source
