17.3 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)
• Interrupt mask flag registers (MK0L, MK0H, MK1L, MK1H, MK2L)
• Priority specification flag registers (PR00L, PR00H, PR01L, PR01H, PR02L, PR10L, PR10H, PR11L, PR11H,
PR12L)
• External interrupt rising edge enable register (EGP0)
• External interrupt falling edge enable register (EGN0)
• Program status word (PSW)
Table 17-2 shows a list of interrupt request flags, interrupt mask flags, and priority specification flags corresponding to
interrupt request sources.
