    PSoC6 - Using SPI functionality along with JTAG

    AnA_4675486

      Hi,

       

      I'm planning to use PSoC 6 (CY8C6247BZI-D54) in one of my designs. In normal operation mode, I planning to use pin 6.4, 6.5, 6.6, and 6.7 for SPI communication with LCD. However, I do need these pins for flashing the PSoC obviously. I'd like to know if there's any special considerations from hardware schematics stand point. Do I need any external pull up/ pull down resistors on the JTAG lines? Or no I can simply connect the 4 pins from PSoC to JTAG connector and LCD without any intermediate components? (Just a side note, I'm only planning to use JTAG for flashing purposes.)

       

      Thanks,
