Figure 11.7 shows the interrupt response time. Interrupt response time is the period between an interrupt request
generation and the end of an interrupt sequence. Interrupt response time is divided into two phases: the period
between an interrupt request generation and the end of the ongoing instruction execution ((a) in Figure 11.7),
and the period required to perform the interrupt sequence ((b) in Figure 11.7).
Time (a) varies depending on an instruction being executed. The DIV, DIVX, and DIVU instructions require the
longest time (a), which is at the maximum of 42 cycles.
Table 11.5 lists time (b).
