Interrupt-causing signals are visible in three state registers.  Most of these are 
unlatched, meaning that a read of the state register shows the actual state of the 
signals at the instant of the read.   

The exceptions are (1) BERR, which is a "sticky" bit, meaning that the bit signifies 
whether BERR had ever been asserted (the VXR register bit), and (2) the TTL trigger 
signals, which for interrupt purposes are taken from the trigger latch register.  The 
convention used is that a 0 bit signifies an asserted (interrupting) state. 

The primary purpose of the state registers is to let the interrupt handler software 
determine which interrupts and events generated the IRQ10 interrupt to the processor.
