VT1433B Interrupt Behavior

Interrupt Setup

The VT1433B VXI module can be programmed to interrupt a host computer using the VME interrupt lines. VME provides seven such lines and the VT1433B module can be told to use any one of them (see e1432_set_interrupt_priority).

The VT1432A can interrupt the host computer in response to different events. A mask of events can be specified on which to interrupt. This mask is created by OR'ing together the various conditions that are desired. The following table, copied from the e1432_set_interrupt_mask manual page, shows the conditions that can cause an interrupt:
