10.5.5 Interrupt Response Time
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 10.5 is set in the IPL. Table 10.5 shows the IPL Level that is Set to IPL when Software or Special
Interrupts is Accepted.
Figure 10.6 shows the Interrupt Response Time. The interrupt response or interrupt acknowledge time
denotes a time from when an interrupt request is generated till when the first instruction in the interrupt
routine is executed. Specifically, it consists of a time from when an interrupt request is generated till when
the instruction then executing is completed ((a) on Figure 10.6) and a time during which the interrupt
sequence is executed ((b) on Figure 10.6).

executing is completed. The length of this time varies with the instruction being
executed. The DIVX instruction requires the longest time, which is equal to 30 cycles
(without wait state, the divisor being a register).

DBC interrupt and 1 cycle for the address match and single-step interrupts.
