14.3 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 (PR00L, PR00H, PR01L, PR01H, PR10L, PR10H, PR11L, PR11H)

 External interrupt rising edge enable register (EGP0)

 External interrupt falling edge enable register (EGN0)

 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.
