_8168_set_int_factor:
The interrupt status of cPCI-8168 is separated by two independent
parts: error type interrupt and event type interrupt. This function
allows users to select event type interrupt factors of each axis. But
the error type interrupt factors of each axis can't be selected
because it is non-maskable when the interrupt service is turned on
by _8168_int_control(). The event interrupt status recodes
the motion and comparator event under normal operation. This
kind of
_8168_set_int_factor(). The error interrupt status is for
abnormal stop of axis. For example: End-limit, ALM ...etc. This
kind of interrupt cannot be masked. The following talbe contains
the definitions of event type interrupt factors. By setting the rela-
tive bit as 1, cPCI-8168 can generate interrupt signal to host PC
when the condition of bit is met.
