Agilent E1432A Interrupt Behavior
Interrupt Setup
For an example of interrupt handling see the program event.c in the
examples directory.
The Agilent E1432A VXI module can be programmed to interrupt a host
computer using the VME interrupt lines. VME provides seven such lines.
Using hpe1432_setInterruptPriority, you can set up the Agilent E1432A
module to use any one of them.
The Agilent 1432A can interrupt the host computer in response to different
events. Using hpe1432_setInterruptMask you can specify a mask of events
on which to interrupt. This mask is created by OR-ing together the various
conditions for an interrupt. The following table shows the conditions that
can cause an interrupt:
Interrupt Mask Bit Definitions
Define (in e1432.h) Description
HPE1432_IRQ_BLOCK_READY Scan of data ready in FIFO
HPE1432_IRQ_MEAS_ERROR FIFO overflow
HPE1432_IRQ_MEAS_STATE_CHANGE Measurement state machine changed state
HPE1432_IRQ_MEAS_WARNING Measurement warning
HPE1432_IRQ_OVERLOAD_CHANGE Overload status changed
HPE1432_IRQ_SRC_STATUS Source channel interrupt
HPE1432_IRQ_TACHS_AVAIL Raw tach times ready for transfer to other
modules
HPE1432_IRQ_TRIGGER Trigger ready for transfer to other modules
