11.1.6.6
Figure 11.6 shows an Interrupt Response Time. The interrupt response time is the period between
an interrupt request generation and the execution of the first instruction in an interrupt routine. An
interrupt response time includes the period between an interrupt request generation and the
completed execution of an instruction (see #a in Figure 11.6) and the period required to perform an
interrupt sequence (20 cycles, see #b in Figure 11.6).
When an interrupt request of a maskable interrupt is acknowledged, the interrupt priority level of the
acknowledged interrupt is set in the IPL.
When a software interrupt and special interrupt request are acknowledged, the value listed in Table
11.5 is set to the IPL. Table 11.5 lists the IPL Value When Software or Special Interrupts Is
Acknowledged.
