GPIO

When working with the SWI mode device of the ATECC608A-TFLXTLS the SCL pin is configured as a general purpose output. The output signal will default to a LOW when the device is initially powered up. The output state can be changed by using the INFO command in GPIO Output mode.

The GPIO can be used as an enable or mode signal to other devices in the system or may be used to drive an LED.

The GPIO signal is not available when the device is an I2C mode device.
