Local Bus Interrupter Enable Register (bits 24-31)
This register is the local bus interrupter enable register. When an enable bit
is high, the corresponding interrupt is enabled. When an enable bit is low,
the corresponding interrupt is disabled. The enable bit does not clear
edge-sensitive interrupts or prevent the flip flop from being set. If
necessary, edge-sensitive interrupters should be cleared to remove any old
interrupts and then enabled.
