    PRTXDR REGISTER

    manuel.julian.moron

      In the Technical reference manual:

         

      http://www.cypress.com/?docID=15539

         

      in page 149 states:

         

       

         

      7:0 Data[7:0]

         

       

         

       

         

       

         

      What means that exactly? I input PRTXDR |=0xFF  (been X from 0 to 4) and I didn't read a high level at any port writed. What I doing wong? have I to put a special command to stand the value in the pin?

         

       

         

      Write value to port or read value from port.

         

      Reads return the state of the pin, not the value in the

         

      PRTxDR register.
