9.1.4 Logical Interrupt Connection Diagram (Internal/External)
Figure 9−1 shows the logical connection of the interrupt sources and its relationship to INT0. The priority
encoder generates an 8-bit vector, corresponding to 64 interrupt sources (not all are used). The interrupt
priorities are hardwired. Vector 0x88 is the highest and 0x12 is the lowest.
