Reference oscillator crystal inputs.
Selected crystal frequency must be
programmed in BR4 to BR0 for correct
baseband filter bandwidth operation.
XTAL pin is used for external reference
input via 10nF capacitor.
Variable I²C address selection allowing
the use of more than one device per I²C
bus system by the voltage on this pin.
See Table 3 for programming details.
