17.3 Registers Controlling Interrupt Functions
The following 6 types of registers are used to control the interrupt functions.
• 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 17-2 shows a list of interrupt request flags, interrupt mask flags, and priority specification flags corresponding
to interrupt request sources.

2. When 8-bit timer/event counter 51 and 8-bit timer H1 are used in the carrier generator mode, an interrupt
is generated upon the timing when the INTTM5H1 signal is generated (see Figure 8-15 Transfer Timing).
