2.2 56F8357 Signal Pins
After reset, each pin is configured for its primary function (listed first). Any alternate functionality
must be programmed.
If the “State During Reset” lists more than one state for a pin, the first state is the actual reset state.
Other states show the reset condition of the alternate function, which you get if the alternate pin
function is selected without changing the configuration of the alternate peripheral. For example,
the A8/GPIOA0 pin shows that it is tri-stated during reset. If the GPIOA_PER is changed to select
the GPIO function of the pin, it will become an input if no other registers are changed.

I/O Power — This pin supplies 3.3V power to the chip I/O
interface.
ADC Power — This pin supplies 3.3V power to the ADC
modules. It must be connected to a clean analog power
supply.
Oscillator and PLL Power — This pin supplies 3.3V
power to the OSC and to the internal regulator that in turn
supplies the Phase Locked Loop. It must be connected to
a clean analog power supply.
VSS — These pins provide ground for chip logic and I/O
drivers.
