Note 19: Reserved Vector x Interrupt for future growth for the number of vectors.
Note 20: Drivers shouldn't allow Sequencer Interrupt and Vector x Interrupt to be set at same time. Sequencer Interrupt has priority over the Vector x Interrupt.
Note 21: Half full or half empty designates 56 long words.
Note 22: This register is writable in debug mode only.
