    CY7C65211A SPI Mode GPIO0/1 Configuration

    JaMa_3208951

      Hello,

       

      When the CY7C65211A is configured as an SPI slave you are able to configure GPIO1/0 for an Rx and Tx LED. I noticed that the LEDs do not start to change state until after a certain amount of clock signals. My question is are these signals fixed where they turn on and off after a certain amount of clock periods?

       

      Thank you,

      Jake

          Hello Jake,

           

          The USB-Serial SPI Rx and Tx notifications are not in sync with the clock signal. They should only be used to notify/indicate that a transfer is ongoing.

           

          LEDs are expected to be connected to the configured GPIOs.

          GPIO 10 (pin 6) is already connected to a LED on CYUSBS234 DVK and can be used to notify the ongoing transfers.

           

          Thanks,
