    UART signal does not received

      Hello Friends, 


      You are always in busy with Creator3.0, I presume.


      Anyway, listen to my trouble of PSoC1.




      UART signal that sent from PSoC1(8C24233) to (FTK3270/MTF Board 8C21434) was not received.


      receive interrupt has not occur.


      UART-Tx signal was lift up 1.7V (look wave1)




      Sender is strong drive and receiver is High-Z input.


      Even if resistive pull-down and pre-buffered by DigBuf 


      was not for help it.




      For an experiment, No load output (look wave2)


      It seems properly.


      Any suggestion in owe you.
