25.7 Interrupt Acknowledge Time of CPU
request signals successively, input the next interrupt request signal at least 5 clocks after the preceding interrupt.
Except the following cases, the interrupt acknowledge time of the CPU is 4 clocks minimum. To input interrupt
• In IDLE1/IDLE2/STOP mode
• When the external bus is accessed
• When interrupt request non-sampling instructions are successively executed (see 25.8
• When the interrupt control register is accessed
(1) Minimum interrupt response time
(2) Maximum interrupt response time
Remark
Interrupts Are Not Acknowledged by CPU.)
