CPU clock
Data bus
(1) The CPU obtains interrupt information (interrupt number and interrupt request level) by reading address
(2) The FLG register, prior to an interrupt sequence, is saved to a temporary register
(3) The I, D and U flags in the FLG register become as follows:
(4) The temporary register
(5) The PC is saved to the stack.
(6) The interrupt priority level of the acknowledged interrupt in IPL is set.
(7) The start address of the relevant interrupt routine set in the interrupt vector is stored in the PC.
An interrupt sequence − what are performed over a period from the instant an interrupt is accepted to the instant
the interrupt routine is executed − is described here.
If an interrupt occurs during execution of an instruction, the processor determines its priority when the
execution of the instruction is completed, and transfers control to the interrupt sequence from the next cycle. If
an interrupt occurs during execution of either the SMOVB, SMOVF, SSTR or RMPA instruction, the processor
temporarily suspends the instruction being executed, and transfers control to the interrupt sequence.
The CPU behavior during the interrupt sequence is described below. Figure 12.5 shows Time Required for
Executing Interrupt Sequence.
After the interrupt sequence is completed, an instruction is executed from the starting address of the interrupt
routine.

000000h. Then, the IR bit applicable to the interrupt information is set to “0” (interrupt requested).
The I flag is set to “0” (interrupt disabled)
The D flag is set to “0” (single-step interrupt disabled)
The U flag is set to “0” (ISP selected)
However, the U flag does not change state if an INT instruction for software interrupt Nos. 32 to 63 is
executed.
