Positive digital supplies. Nominally +5 volts.
Pin 58 is an analog supply pin used for the internal PLL but may be connected to the digital
supply pins under most circumstances.
GND - Digital Ground, PINS 10, 21, 27, 40, 50, 57.
Digital ground supplies.
Pin 57 is an analog ground pin used for the internal PLL but may be connected to the digital
ground pins under most circumstances.
