5.2
Table 5.1 summarizes the pins of the interrupt controller.
Table 5.1
5.3
The interrupt controller has the following registers. For details on the system control register
(SYSCR), see section 3.2.2, System Control Register (SYSCR), and for details on the IRQ sense
port select register (ISSR), see section 8.11.2, IRQ Sense Port Select Register (ISSR).
• Interrupt control registers A to C (ICRA to ICRC)
• Address break control register (ABRKCR)
• Break address registers A to C (PBARA to PBARC)
• IRQ sense control registers H, L (ISCRH, ISCRL)
• IRQ enable register (IER)
• IRQ status register (ISR)
5.3.1
The ICR registers set interrupt control levels for interrupts other than NMI.
The correspondence between interrupt sources and ICRA to ICRC settings is shown in table 5.2.

Maskable external interrupts
Rising edge, falling edge, or both edges, or level sensing, can
be selected individually for each pin. Whether the IRQn
interrupt is input from the IRQn or (IRQn) is selectable.
