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 19-2 shows a list of interrupt request flags, interrupt mask flags, and priority specification flags corresponding

If either interrupt source INTCSI10 or INTST0 is generated, bit 2 of IF0H is set (1).
Bit 2 of MK0H supports both interrupt sources INTCSI10 and INTST0.
Bit 2 of PR0H supports both interrupt sources INTCSI10 and INTST0.
