14.3 Registers Controlling Interrupt Function
The following 6 types of registers are used to control the interrupt functions.
•
Interrupt request flag register (IF0L, IF0H, IF1L)
•
Interrupt mask flag register (MK0L, MK0H, MK1L)
•
Priority specification flag register (PR0L, PR0H, PR1L)
•
External interrupt rising edge enable register (EGP)
•
External interrupt falling edge enable register (EGN)
•
Program status word (PSW)
Table 14-2 shows a list of interrupt request flags, interrupt mask flags, and priority specification flags corresponding
to interrupt request sources.

PD78F0102H and 78F0103H. If either of the two types of interrupt sources is
generated, these flags are set (1).
