ADLINK PCI-8258 - Manual (Page 214)

200 Motion Control Theory
Axis interrupt type contains all control axis relevant events. The
digital input interrupt contains rising edge interrupt and falling edge
interrupt. And other events are contained in system interrupt type.
See table below for all interrupt event types contained in this
controller. Here items 0~7 are interrupt relevant to each control
axis, item 8 is system relevant interrupt and item 9 and 10 are
digital input interrupt. (Note: For PCI-8254 items 0~3 and 4~7 are
reserved.)
• Interrupt Item overview:I
Each item can have up to 32 kinds of interrupt events (32 bit). See
tables below for detailed definitions.
