IRQ

The 2IQEC2/4 card allows the use of interrupts (IRQ) 2-7, 10-12, 14, and 15. This interrupt is shared with all the channels. To determine the channel that caused the interrupt, the interrupt service routine must read the address located at the base address plus 8. The lower nibble will indicate which channel caused the interrupt. Where bit 0 is the X-Axis, bit 1 is the Y-Axis, bit 2 is the Z- Axis, and bit 3 is the W-Axis. The upper nibble is not used. To clear the interrupt, the interrupt service routine must read or write to the address located at base address plus 12 (0xC). The IRQ is set by placing a jumper on JP1. Only one jumper should be placed on JP1 at any one time. Check Table 3 for common interrupt uses.

The conditions required to generate an interrupt can be selected by the use of jumpers. Each axis is independently configured. Note that more than one condition can be configured to generate the interrupt. Note that the use of an interrupt is not required.
