Section 5 Interrupt Controller (INTC)
An example of connections for external vector mode interrupts is shown in figure 5.2, and an
example of connections for auto-vector mode interrupts in figure 5.3.

Figure 5.3 Example of Connections for Auto-Vector Mode Interrupts
Figures 5.4 to 5.7 show the interrupt vector fetch cycle for the external vector mode. During this
cycle, CS0–CS4 stay high. A24–A4 output undefined values. The WAIT pin is sampled, but
programmable waits are not valid.
