Interrupt Mode

NOTE To read the interrupt flag status, refer to the

HPE6432_GetInterruptFlags() function.

When running the synthesizer in list mode, there are seven interrupt

causes that can be output on any of the seven VXI backplane interrupt

request lines (IRQ1- IRQ7), but only two can be controlled by the user.

When running the synthesizer in set-spot mode, a Settled Interrupt is

always generated after a list point has settled, but none of the interrupt

causes can be directly controlled by the user in this mode.

Interrupt modes have no affect on how a list is traversed. They enable

or disable interrupts generated by the synthesizer. These interrupts are

processed by the VXIplug&play driver, and it may be possible for a user

to redefine or supercede the Interrupt Service Routine that is provided.

CAUTION Using these interrupts with triggers having a high

repetition-rate may exceed the ability of the host computer to

service the interrupts in a timely fashion; this could cause the

host to appear non-responsive to user inputs. This depends on

the system configuration, the user’s application software, and

the performance resources of the host computer.
