The IA88C00 supports as many as 27 interrupt sources. Interrupt sources are sorted into 8 different
priority levels. These levels are controlled by the interrupt Priority Register (IPR). Enabling and masking
of individual interrupts is controlled by the System Mode Register (R222).
The various sources, vectors and levels of the interrupt structure are depicted in Figure 58 in this section.
