12.3 Registers Controlling Interrupt Functions

The following six types of registers are used to control the interrupt functions.
• Interrupt request flag register (IF0L, IF0H)
• Interrupt mask flag register (MK0L, MK0H)
• Priority specification flag register (PR0L, PR0H)
• External interrupt rising edge enable register (EGP)
• External interrupt falling edge enable register (EGN)
• Program status word (PSW)
Table 12-2 gives a listing of interrupt request flags, interrupt mask flags, and priority specification flags
corresponding to interrupt request sources.
