104X Address and IRQ Switch Locations
Set Base I/O Address
Use the SW1 dipswitch on each controller to set the base I/O address.
Set the Interrupts
Interrupts may be generated from the DSP Series controller to the host CPU. SW2 connects the
controller’s interrupt circuitry to one of the host CPU’s IRQ lines. To use one of the IRQ lines,
you must configure switch SW2. Configure switch SW2 for the interrupt (IRQ2, IRQ3, ...) that
you want the 104X to use.
