Each Coincidence Compare output is designed to generate its own independent
interrupt. The Coincidence Compare #1 output pulse will generate the INT2 interrupt.
The Coincidence Compare #2 pulse will generate the INT3 interrupt. For more
information see section 2.4.10.
2.4.10 VME INTERRUPT CONTROL
The heart of the Interrupt Control logic is the Bus Interrupter Module (BIM). It handles
up to 4 independent sources of interrupt requests and is fully programmable directly
over the VME bus. When the system interrupt handler or processor responds with an
interrupt acknowledge cycle, the BIM chip can respond supplying an interrupt vector.
Control and setup is facilitated by a separate control register for each interrupt source.
This manual includes programming examples in section 2.5 that show how to setup the
BIM for various interrupting sources with priority and vector setup.
