作为NV数字配置位备用NV数字电位器

资料介绍
摘要:一些数字系统控制位设置为高或低取决于系统的配置。一个常见的例子是在一台PC配置跳线或DIP开关设置光盘驱动器是一个ISA总线上的船长或奴隶。在其他应用程序,这些配置位可启用或禁用功能,如马达驱动器或灯泡时功率为允许处理器时间采取控制系统,使安全或电源预算的原因,有秩序地功能。本应用笔记演示如何备用非易失(NV)数字电位器可以用于数字配置位。

APPLICATION NOTE 235
Using Spare NV Digital Pots as NV Digital Configuration Bits

Abstract: Some digital systems have control bits that are set to HI or LO depending on the configuration of the
system. A common example in a PC is a configuration jumper or dipswitch that sets which disc drive is the
master or slave on an ISA bus. In other applications, these configuration bits may enable or disable a function
such as a motor drive or lamp a during power-up to allow a processor time to take control of the system and
enable functions in an orderly manner for safety or power budgeti……
