    I2C pins dont work on all ports

    jasonkahana_1482786

      I have been using PSoC5 for a series of scientific instruments, and I have noticed something strange- when I assign my I2C pins to ports0[0]-0[7], they don't work.  I have them pulled up.  Strangely, when I move them to pins 2.3 and 2.4 with absolutely no other changes in the code, the communication works properly.  I noticed something similar with SPI as well.  Creator doesn't seem to indicate that I shouldn't be using those pins for communications.  Can anyone tell me why this is happening.  It doesn't seem to be happening with a PSOC4M.

         

       

         

      Thanks!
