Advanced Interrupt Controller Signals
The inputs can be used synchronously or asynchronously (in relation to MCKI).
For synchronous AIC inputs, certain setup/hold constraints must be met. These constraints are shown in Table 22 and are
represented in Figure 9.
For asynchronous inputs, a minimum pulse width is necessary as shown in Table 23 and as represented in Figure 9.
