4.5 The Counters
4.5.1 Preset Command position counter
The preset command position counter is a 24-bit binary down-
count counter. It provides the information of the current command
counts which are not outputted.
4.6 Interrupt Control
The motion controller can generate an interrupt signal to the host
PC. It is much useful for event-driven software application. There
are two kinds of interrupt sources on PCI-8144. One is motion
interrupt source and the other is GPIO interrupt sources. Motion
and GPIO interrupt sources can be maskable. Motion interrupt
sources can be maskable by
_8144_set_motion_interrupt_factor()
. Its mask bits are
shown as following table:
