In all configurations in which GPIO[7] is enabled as output:
a) the GPIO[7] 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[7] 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[7] pin is a rail to rail output supplied by V
GPIO_SPI.
