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
