(1) Half full or half empty designates 56 long words.
(2) 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.
(3) Reserved Vector x Interrupt Enable for future growth for the number of vectors.

Vector Interrupt Enable<2:0> Vector "x" complete interrupt enable, where "x" is the vector number, a binary encoding of bits
<2:0>. Only vector interrupts 1 through 4 are valid. Vector interrupts 5 through 7 reserved for future
use.
