In all configurations in which GPIO[6] is enabled as output:
a) the GPIO[6] 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[6] 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[6] pin is a rail to rail output supplied by V
GPIO_SPI.
