2 PC13 bidirectional GPIO PC13 (TAMPER-RTC) powered through a power switch that can source only 3 mA, so it must not drive current-source loads such as LEDs when used as output.
3 PC14 bidirectional GPIO PC14 (LEXT_IN) powered through a power switch limited to 3 mA source current, so it must not drive current-source loads when used as output.
4 PC15 bidirectional GPIO PC15 (LEXT_OUT) powered through a power switch limited to 3 mA source current, so it must not drive current-source loads when used as output.
