21.3 Registers Controlling Interrupt Functions
The following 9 types of registers are used to control the interrupt functions.
 Interrupt request flag registers (IF0L, IF0H, IF1L, IF1H, IF2L, IF2H, IF3L)
 Interrupt mask flag registers (MK0L, MK0H, MK1L, MK1H, MK2L, MK2H, MK3L)
 Priority specification flag registers (PR00L, PR00H, PR01L, PR01H, PR02L, PR02H, PR03L, PR10L, PR10H, PR11L,
PR11H, PR12L, PR12H, PR13L)
 External interrupt rising edge enable registers (EGP0, EGP1)
 External interrupt falling edge enable registers (EGN0, EGN1)
 Interrupt source determination flag register 0 (INTFLG0)
 Interrupt mask register (INTMSK)
 Input switch control register (ISC)
 Program status word (PSW)
Table 21-2 shows a list of interrupt request flags, interrupt mask flags, and priority specification flags corresponding to
interrupt request sources.
