The SWI device version of the ATECC608A-TFLXTLS has a single GPIO pin configured as an output buffer. The output will default to a LOW value upon device power-up. The value of this output can be changed by using the INFO Command in GPIO Write mode.
Upon successful completion the command will return a four byte response with the LSB indicating the value that the output was written to. If the command fails then a single error code byte will be returned.
