Note 16: Reserved Vector x Interrupt Enable for future growth for the number of vectors.
Note 17: Drivers should not allow Sequencer Interrupt Enable and Vector x Interrupt Enable to be set at same time. Sequencer Interrupt Enable has priority over
the Vector x Interrupt Enable.
Note 18: Half full or half empty designates 56 long words.
