18.3 Registers Controlling Interrupt Functions
The following 6 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)
● External interrupt falling edge enable registers (EGN0)
● Program status word (PSW)
Table 18-2 shows a list of interrupt request flags, interrupt mask flags, and priority specification flags corresponding to
interrupt request sources.

Note If one of the interrupt sources INTST0, INTCSI00, and INTIIC00 is generated, bit 5 of the IF0H register is
set to 1. Bit 5 of the MK0H, PR00H, and PR10H registers supports these three interrupt sources.
