Table 33. Priority Levels
A low-priority interrupt is always interrupted by a higher priority interrupt but not by another inter-
rupt of lower or equal priority. Higher priority interrupts are serviced before lower priority
interrupts. The response to simultaneous occurrence of equal priority interrupts is determined by
an internal hardware polling sequence detailed in Table 34. Thus within each priority level there
is a second priority structure determined by the polling sequence. The interrupt control system is
shown in Figure 10-1.
