Preliminary User’s Manual U14581EJ3V0UM00
19.3 Interrupt Function Control Registers
The following six 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 specify flag register (PR0L, PR0H, PR1L)
• External interrupt rising edge enable register (EGP)
• External interrupt falling edge enable register (EGN)
• Prescaler mode register (PRM0)
• Program status word (PSW)
Table 19-2 gives a list of interrupt request flags, interrupt mask flags, and priority specify flags corresponding to
interrupt request sources.
