Logical Interrupt Connection Diagram (Internal/External)
Figure 9–1 shows the logical connection of the interrupt sources and its relation with XINTO. The priority encoder
generates an 8-bit vector, corresponding to 64 interrupt sources (not all are used). The interrupt priorities are hard
wired. Vector 0x88 is the highest and 0x12 is the lowest.
