This register controls the VMEbus interrupter vector.
is used. Normal VMEbus interrupts should never be
cleared. This bit always reads 0 and writing a 0 to
this bit has no effect.
These bits control the function of the IRQ1 signal
line on the VMEbus:
0 The IRQ1 signal from the interrupter is
connected to the IRQ1 signal line on the
VMEbus.
1 The output from tick timer 1 is connected to
the IRQ1 signal line on the VMEbus.
2 The IRQ1 signal from the interrupter is
connected to the IRQ1 signal line on the
VMEbus.
The output from tick timer 2 is connected to
3
the IRQ1 signal line on the VMEbus.
