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)
• Interrupt mask flag registers (MK0L, MK0H, MK1L, MK1H)
• Priority specification flag registers (PR0L, PR0H, PR1L, PR1H)
• External interrupt rising edge enable registers (EGPCTL0, EGPCTL1)
• External interrupt falling edge enable registers (EGNCTL0, EGNCTL1)
• 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.
