46. Routing The ElanSC400 microcontroller provides internal interrupt request IRQ and direct memory access DMA functions traditionally provided by discrete 8259 programmable interrupt controller PIC and 8237 DMA controller DMAC devices However to minimize pin count and thus system cost only two of the seven possible PC AT compatible DMA channels are available externally to the ElanSC400 microcontroller and at most there are eight possible IRQ inputs of which two can be routed to the ISA connectors on the evaluation board Software can control which internal interrupt level or DMA channel the external IRQ or DMA pins are used for inside the lanSC400 microcontroller This is done via two configuration status and control CSC register ports 22h and 23h For example the evaluation board BIOS normally programs these registers so the programmable pins PDRQO and PDACKO are routed internally to DMA channel 2 which is used for the floppy disk controller in a typical PC AT system On the ElanSC400 microcontroller evaluation board the two available PIRQ signals can be routed separately to any of the eleven ISA bus IRQ pins The two DMA channels are normally used for the floppy diskette and audio interfaces but you can switch either channel to the ISA bus instead When used for ISA either programmable DMA channel can be routed by jumpers to any of the seven ISA bus DMA channels The following sections explain how to route these signals phy
