2.7 Interrupt Program
An interrupt program is from an interrupt pointer (I) to the IRET instruction.
The interrupt pointer number (I) varies depending on the interrupt factor. ( Page 273, Section 5.10) When an
interrupt factor occurs, an interrupt program of the interrupt pointer number corresponding to that factor is executed.
(Interrupt program are executed only after the corresponding interrupt factor occurs.)
