•
Interrupt request flag register (IF0L, IF0H, IF1L, IF1H)
•
Interrupt mask flag register (MK0L, MK0H, MK1L, MK1H)
•
Priority specification flag register (PR0L, PR0H, PR1L, PR1H)
•
External interrupt rising edge enable register (EGP)
•
External interrupt falling edge enable register (EGN)
•
Program status word (PSW)
Table 13-2 shows a list of interrupt request flags, interrupt mask flags, and priority specification flags corresponding
