    I couldn’t find the actual pinout for the 8 pin package, but the block diagrams make me think they’re power, ground, and 6 general purpose pins which can all be GPIO. Other functions, like ADC, SPI and I2C (all of which it has) will be secondary or tertiary functions on those same pins, selected in software.

    So the actual answer you’re looking for is basically that all of the pins are everything, and the pinout is almost entirely software defined
