Figure 12.7 shows the Interrupt Response Time. The interrupt response time is the period between an interrupt
request generation and the execution of the first instruction in the interrupt routine. The interrupt response time
includes the period between interrupt request generation and the completion of execution of the instruction
(refer to (a) in Figure 12.7) and the period required to perform the interrupt sequence (20 cycles, refer to (b) in
Figure 12.7).
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 or special interrupt request is acknowledged, the level listed in Table 12.5 is set in the
IPL.
Table 12.5 lists the IPL Value When Software or Special Interrupt Is Acknowledged.
