Analog ground
25MHz crystal or oscillator clock connection.
Pins (X1, X2) connect to a crystal. If an oscillator is used, X1 connects to a 3.3V
tolerant oscillator and X2 is a no connect.
Note: Clock requirement is ± 50ppm for either crystal or oscillator.
Hardware reset pin (active Low). This reset input is required minimum of 10ms low
after stable supply voltage 3.3V.
