1. AUX1Enable or AUX1System bit =1 represent the case in which AUX1 is used as a system or not system
regulator.

2. In all configurations in which GPIO[1] is enabled as output:
a) the GPIO[1] pin can be always used as an analog input to the ADC system (ADC function) by writing
its address in the A2DChannelX[4:0] in the A2DConfigX register and starting a conversion;
b) the GPIO[1] pin can be always used as a digital input so its value can be always read through SPI
interface (SPI_IN function);
c) the GPIO[1] pin is an open drain output.
