1. Function availability depends on the chosen device.
2. NC (not-connected) pins are not bonded. They must be configured by software to output push-pull and forced to 0 in the
output data register to avoid extra current consumption in low power modes.
3. PC13, PC14, PC15 and PI8 are supplied through the power switch. Since the switch only sinks a limited amount of current
(3 mA), the use of GPIOs PC13 to PC15 and PI8 in output mode is limited:
- The speed should not exceed 2 MHz with a maximum load of 30 pF.
- These I/Os must not be used as a current source (e.g. to drive an LED).
