    AVNET SPARTAN 3A Eval KIT : No output from PSoC.

    venkatesan.s
              Hai,   
         
      I am working on AVNET SPARTAN 3A Evaluation KIT.   
      I just used a 26bit counter code in the FPGA and   
      I send the MS 3 bits of the counter to the PSoC.   
      In the PSoC , I just forward the input signal to   
      the output port.   
         
         
      The input pins of teh PSoC are P2(5), P2(7) and   
      P4(6) which are connected with the FPGA I/Os.   
      The output pins of the PSoC are P0(1), P0(3)   
      and p0(5) , which are connected with the   
      connector J9.   
         
      I am noticing the counter signal at the input   
      of the PSoC, But not at the Output pins.   
         
      I have given the PSoC main.c code below.   
      If it is required I can give the VHDL code also.   
         
      Please help me, to find out the problem   
      with my code.   
         
      Thank You.
