Figure 5.3.1. Interrupt response time
Table 5.3.1 Interrupt Sequence Execution Time
*1 Add two cycles for the DBC interrupt. Add one cycle for the address match and single-step interrupts.
*2 Allocate interrupt vector addresses in even addresses as must as possible.

5.3.1 Interrupt Response Time
(a) Time from when interrupt request is generated to when the instruction then under execution is completed
(b) Time in which the interrupt sequence is executed
The interrupt response time means a period of time from when an interrupt request is generated till when
the first instruction of the interrupt routine is executed. This period consists of time (a) from when an
interrupt request is generated to when the instruction then under way is completed and time (b) in which
an interrupt sequence is executed. Figure 5.3.1 shows the interrupt response time.
Time (a) varies with each instruction being executed. The DIVX instruction requires a maximum time
that consists of 30 cycles (without wait state) .
Time (b) is shown below.
