Figure 9.6 shows the interrupt response time. The interrupt response or interrupt acknowledge time
denotes the time from when an interrupt request is generated till when the first instruction in the interrupt
routine is executed. Specifically, it consists of the time from when an interrupt request is generated till
when the instruction then executing is completed ((a) in Figure 9.6) and the time during which the inter-
rupt sequence is executed ((b) in Figure 9.6).
When a maskable interrupt request is accepted, the interrupt priority level of the accepted interrupt is set
in the IPL.
When a software interrupt or special interrupt request is accepted, one of the interrupt priority levels listed
in Table 9.5 is set in the IPL. Shown in Table 9.5 are the IPL values of software and special interrupts
when they are accepted.

(without wait state, the divisor being a register).
