4.10 Interrupt Control
The 8164 motion controller can generate an INT signal to the host
PC. The parameter, “intFlag,” of the software function
_8164_int_control(), can enable/disable the interrupt ser-
vice.
After a interrupt occurs, the function _8164_get_int_status()
is used to receive the INT status, which contains information about
the INT signal. The INT status of the 8164 comprises of two inde-
pendent parts: error_int_status and event_int_status.
The event_int_status recodes the motion and comparator
event under normal operation. This INT status can be masked by
_8164_set_int_factor(). The error_int_status is for abnor-
mal stoppage of the 8164 (i.e. EL, ALM, etc.). This INT cannot be
masked. The following are the definitions of the two int_status:
error_int_status: can be masked by function call
_8164_int_factor()
