1. Please refer to the recommendations for implementing the low power mode in section 2.5 Low-Power Implementation in the AN92584.
2. Please make sure that the debugging was disabled in the project to reduce current consumption. In Design Wide Resources Go to "system" view and change the "Debug Select" to GPIO.
3. Please put the GPIO pins to Analog High Z mode whenever pins are not used and can switch back to normal drive mode when pins are used. Please refer to the section 6.3 GPIOs in AN86233.
