IRQ SUPPORT The following IRQs are available on the PC/104 bus: IRQ 3, IRQ 4, IRQ 5, IRQ 10. Each of the four IRQs must be enabled in the CMOS setup screen before they can be used on the ISA bus. DMA SUPPORT The current revision of the board does not support PC/104 DMA.The lower 1 MB memory map of the EPIC-2 is arranged as shown in the following table. Various blocks of memory space between C0000h and FFFFFh can be shadowed. The CMOS setup is used to enable or disable this feature.The following table lists the common I/O devices in the EPIC-2 I/O map. User I/O devices should be added using care to avoid the devices already in the map as shown in the following table.

Note: Rev 4.04 boards and later support 16-bit I/O transfers. On Rev 4.03 and earlier boards, all 16-bit I/O reads and writes were converted into two 8-bit cycles (low byte, then high byte) on the PC/104 bus.

Interrupt Configuration

 The EPIC-2 has the standard complement of PC type interrupts. Four non-shared interrupts are routed to the PC/104 bus, and up to four IRQ lines can be allocated as needed to PCI devices. There are no interrupt configuration jumpers. All configuration is handled through the CMOS setup. The switches in Figure 10 indicate the various CMOS setup options. Closed switches show factory default settings. Note: If your design needs to use interrupt lines on the PC/104 bus, IRQ5, and/or IRQ10 are recommended. (IRQ3 and IRQ4 are normally used by COM1 and COM2 on the main board)

A watchdog timer circuit is included

 on the EPIC-2 board to reset the CPU if proper software execution fails or a hardware malfunction occurs. The watchdog timer is controlled by the SCR. If the watchdog timer is enabled, software must periodically refresh the watchdog timer at a rate faster than the timer is set to expire (1000 ms minimum). Writing 5Ah to WDHOLD resets the watchdog timeout period.
