    UART Pins do not function as GPIO

    andrew.ong_1675156

      On the PSoC5 CY8C5888LTI-LP097, there are pins marked UART on 12_6 and 12_7. When I configured these to be regular digital input pins down pull-down resistors, one pin was permanently HIGH and one was permanently LOW. 

         

      I have a UART in my project, but it's TX only and I connected it to 1_7, not 12_6. 

         

      I didn't read anything in the app notes about UART pins.  I'm using the pins marked I2C and they work fine.
