The objective is to set up SPI communication between VTI Technologies digital pressure sensor component and an MCU of an application device ATMEGA16L. In this code example: ?The MCU is configured ?SCP1000-D01 is initialized and configured ?The high resolution measurement mode is activated ?Temperature and pressure information is read always when the DRDY pin is in high state Please refer to the document "SCP1000 Product Family Specification 8260800" for further information on SCP1000 register addressing and SPI communication. This document applies to the SCP1000-D01.

DES工作的基本原理是，其入口参数有三个:key、data、mode。 key为加密解密使用的密钥，data为加密解密的数据，mode为其工作模式。当模式为加密模式时，明文按照64位进行分组，形成明文组，key用于对数据加密，当模式为解密模式时，key用于对数据解密。实际运用中，密钥只用到了64位中的56位，这样才具有高的安全性。
