Four digital input pins (ENABLE, DATA, BAND, and MODE) enable the circuit to be controlled by a microcontroller. The
band frequency and the modulation type should be configured before enabling the circuit.
One digital output pin, DATACLK, provides the microcontroller with a reference frequency for data clocking. This frequency
is equal to the crystal oscillator frequency divided by 64 (see
