MOTOROLA
After every instruction, the CPU checks all pending interrupts if the I bit
is not set. If more than one interrupt is pending when an instruction is
done, the highest priority interrupt is serviced first. In the example shown
in
service routine, the pending interrupt is serviced before the LDA
instruction is executed.
