5.3 Interrupt Sequence
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.
In the interrupt sequence, the processor carries out the following in sequence given:
After the interrupt sequence is completed, the processor resumes executing instructions from the first ad-
dress of the interrupt routine.
Note: This register cannot be utilized by the user.
Chapter 5
(1) CPU gets the interrupt information (the interrupt number and interrupt request level) by reading address
(2) Saves the content of the flag register (FLG) as it was immediately before the start of interrupt sequence
(3) Sets the interrupt enable flag (I flag), the debug flag (D flag), and the stack pointer select flag (U flag) to
(4) Saves the content of the temporary register (Note 1) within the CPU in the stack area.
(5) Saves the content of the program counter (PC) in the stack area.
(6) Sets the interrupt priority level of the accepted instruction in the IPL.

in the temporary register (Note) within the CPU.
“0” (the U flag, however does not change if the INT instruction, in software interrupt numbers 32
through 63, is executed)
