17.8 Interrupt Response Time of CPU
signals successively, input the next interrupt request signal at least 4 clocks after the preceding interrupt.
704
Instruction (start instruction of interrupt servicing routine)
Except the following cases, the interrupt response time of the CPU is 4 clocks minimum. To input interrupt request
• In IDLE/STOP mode
• When interrupt request non-sampling instructions are successively executed (see 17.9 Periods in Which CPU
• When an on-chip peripheral I/O register is accessed
