    Using SCB UART with LVTTL input threshold for Rx

    user_246598725
              Hi, I need to interface a 3.3V device via UART to PSoC4, which is supplied with 5V. The 3.3V device will accept 5V input on it's Rx line. The PSoC 4 can handle the 3.3V input, but only if the corresponding port pin threshold is set to LVTTL. The problem is that the SCB UART component doesn't show the Rx/Tx pin connections, so there seems no way to configure the Rx pin. Does anyone know a way to configure the pin? Or do I have to copy the SCB component and modify it to show the pins? Regards, Ralf
