CHAPTER 12 EXTERNAL INTERRUPT CIRCUIT

12.1 Overview

12.1 Overview
The external interrupt circuit detects edges on the signal that is input to the
external interrupt pin, and outputs interrupt requests to the interrupt controller.
■ Function of External Interrupt Circuit
The external interrupt circuit detects any edge of a signal that is input to an external interrupt
pin and generates interrupt requests to the interrupt controller. The interrupt generated
according to this interrupt request can cause the device to wake up from standby mode and
return to its normal operating state. Therefore, the operating mode of the device can be
changed when a signal is input to the external interrupt pin.
