1 Introduction
Kinetis L series have ARM
®
Cortex
™
-M0+ core and common
peripheral set, providing multiple power mode and high
efficiency. It has ultra-efficient processor, ultra low-power
mode and energy-saving peripherals, which help the designers
to boost product performance and extend battery life.
An engineer who is familiar with S08 device design and
development might face new challenging tasks from 8-bit to
32-bit microcontrollers (MCU).This application note will help
the users to easily handle those challenges by providing
guidelines to migrate code from the S08 devices to Kinetis L
series of devices.
This document also covers key differences between S08
devices and L family, which include the boot sequence,
interrupt control, power modes, and so on. The example code
snippet is also provided to help shorten the learn curve. The
code snippets are written with IAR Embedded Workbench
6.40.
