AUX1Enable or AUX1System bit =1 represent the case in which AUX1 is used as a System or Not System

regulator.

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);

the GPIO[1] pin is an open drain output.
