5.1
• Two interrupt control modes
• Priorities settable with IPR
• Independent vector addresses
• Seven external interrupts (NMI, IRQ7, and IRQ4 to IRQ0)
• DMAC control
⎯ Any of two interrupt control modes can be set by means of the INTM1 and INTM0 bits in

the source to be identified in the interrupt handling routine.
edge can be selected for NMI. Falling edge, rising edge, or both edge detection, or level
sensing, can be selected for IRQ7 and IRQ4 to IRQ0. IRQ6 is an interrupt only for the on-
chip USB. IRQ5 is an interrupt only for the on-chip RTC.
