Hi, 

  客户IO口不够用,需要使用SWD IO 作为IO口,请问用作IO输出口硬件设计上需要注意什么? 我看说明上说只能烧写不能debug,说的是不能仿真吗?还是只有这两个IO口不可以仿真?

谢谢!

是不能仿真,整个片子的所有功能不能仿真。

仿真的时候,仿真器是通过这两个IO与PSoC通信的。

Setting the SWD pins to GPIO disables the internal debug mechanisms. You can only choose between debugging or alternately GPIO mode of the SWD pins. Of course you may use for test purposes different pins until the functionality is completely debugged and runs error-free.
