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)
• Interrupt mask flag registers (MK0L, MK0H, MK1L)
• Priority specification flag registers (PR00L, PR00H, PR10L, PR10H, PR01L, PR11L)
• External interrupt rising edge enable register 0 (EGP0)
• External interrupt falling edge enable register 0 (EGN0)
• Program status word (PSW)
Tables 14-3 and 14-4 show a list of interrupt request flags, interrupt mask flags, and priority specification flags
corresponding to interrupt request sources.

Note If interrupt source INTST0, INTCSI00, or INTIIC00 occurs, bit 3 of the IF0L register is set to 1.
Bit 3 of the MK0L, PR00L, and PR10L registers supports these three interrupt sources.
