Interrupt Level Selection

There are two sets of jumpers for interrupt selection on the PC-TIO-10 board. W1 is used for
selecting the interrupt level, while W2 is used for local selection of two of the counter outputs as
interrupt sources. The locations of these jumpers are shown in Figure 2-1.
The PC-TIO-10 board can connect to any one of six interrupt lines of the PC I/O Channel:
IRQ3, IRQ4, IRQ5, IRQ6, IRQ7, or IRQ9. You select the interrupt line by setting a jumper on
W1. The default interrupt line is IRQ5. To change to another line, remove the jumper from
IRQ5 and place it on the pins for another request line. Figure 2-3 shows the default factory
setting for IRQ5.
