Resetting MCUs
By Ross Mitchell MCU Applications Motorola Ltd. East Kilbride, Scotland
Introduction
A simple function such as reset can cause many problems since different applications impose very different conditions on the start up and power down of the microcontroller unit (MCU). This document covers the main issues relating to reset and aims to lead the user of the M68HC05 and M68HC11 devices to a safe a reliable approach for the application. Reset in its most basic function ensures that the MCU starts executing code in a controlled manner once power is applied.
