DP83826I 实现EtherCAT通讯应当选择何种模式?BASIC mode or ENHANCED mode? 

是否可以做到不更改PHY的配置,仅通过hardware boot strap实现EtherCAT?

  • 您好,datasheet中有介绍,enhanced mode除了满足basic mode 下的所有以太网应用之外还能满足实时以太网应用。区别在于enhanced mode除了通过stap pin进行配置之外,还需要对寄存器进行配置,这里有一篇关于How and Why to Use the DP83826E for EtherCAT® Applications的应用手册,希望对您有所帮助:
