13 Reference Schematics
The following schematics show the most basic implementation of the PCI1520 possible. These schematics provide minimum functionality. All interrupts are routed using IRQSER.
| NOTE: THESE ARE THE PCI TERMINALS. PLEASE REFER TO SECTION 4 |
3.3VCC | FOR INFORMATION ON WHICH TERMINALS NEED PULLUP RESISTORS. |
