When using EXMs with configurable interrupts, DMA channels, I/O
addresses, and/or memory addresses, avoid conflicts with built-in functions of
the EPC-26A/27. Guidelines are:
1. If an interrupt is needed, use IRQ3, IRQ5, IRQ9, IRQ12, or IRQ15.
IRQ7 can be used if a printer port is not being used. IRQ3 should
not be used if the COM2 port is being used.
2. Use DMA channels 1, 3, 6, and 7.
3. Do not select I/O addresses that conflict with those in the EPC-
26A/27. A complete list appears in Appendix A. For instance, I/O
addresses in the 300-33F range can be used.
4. If the EXM needs to use upper memory addresses, they must be
in the 0C8000-0EFFFF range.
