Section 3 Exception Handling
3.2
Interrupts are controlled by the following registers.
• Interrupt edge select register 1 (IEGR1)
• Interrupt edge select register 2 (IEGR2)
• Interrupt enable register 1 (IENR1)
• Interrupt enable register 2 (IENR2)
• Interrupt flag register 1 (IRR1)
• Interrupt flag register 2 (IRR2)
• Wakeup interrupt flag register (IWPR)
3.2.1
IEGR1 selects the direction of an edge that generates interrupt requests of pins NMI and IRQ3 to
IRQ0.
