18.3 Registers Controlling Interrupt Functions
The following 7 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)
Port alternate switch control registers (MUXSEL)
External interrupt rising edge enable registers 0, 1 (EGPCTL0, EGPCTL1)
External interrupt falling edge enable registers 0, 1 (EGNCTL0, EGNCTL1)
Program status word (PSW)
Table 18-2 shows a list of interrupt request flags, interrupt mask flags, and priority specification flags corresponding to
interrupt request sources.

Note When 8-bit timer/event counter 51 is used in the carrier generator mode, an interrupt is generated upon the
timing when the INTTM5H1 signal is generated (refer to Figure 9-13 Transfer Timing).
