Interrupt Controller
9-2
9.1 Overview
The interrupt controller processes non-maskable interrupts and level interrupts (internal interrupts and external
interrupts).
For external pins, the microcontroller has eight external interrupt pins and one non-maskable interrupt pin.
9.2 Features
• Up to four interrupt requests can be accepted by each group.
• Interrupt priority level: Can be set for each interrupt group.
• External pin interrupt conditions: Positive edge, negative edge, "H" level, "L" level
Recovery from STOP, HALT or SLEEP mode is possible by means
of an external pin interrupt
