19.3 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)
• IInterrupt mask flag registers (MK0L, MK0H, MK1L, MK1H, MK2L, MK2H)
• Priority specification flag registers (PR00L, PR00H, PR01L, PR01H, PR02L, PR02H, PR10L, PR10H, PR11L,
PR11H, PR12L, PR12H)
• External interrupt rising edge enable registers (EGP0, EGP1)
• External interrupt falling edge enable registers (EGN0, EGN1)
• Program status word (PSW)
Tables 19 - 3 to 19 - 5 show a list of interrupt request flags, interrupt mask flags, and priority specification flags
corresponding to interrupt request sources.
