Set to 1 for Tx/Rx channel counter test mode
Set to 0 for normal application
Set to 1 for both AD in and D in pins inputting the transmit 16–bits data and receive 16–bits data
Set to 0 for normal application interfacing with MCU serial peripheral interface. Does not use AD in pin;
If set to 1, REF out output frequency is equal to OSC out
If set to 0, REF out output is OSC out
If set to 1, the transmit counter, transmit phase detector, and the associated circuitry is in power–
Tx PS/f Tx is set “High”.
If set to 1, the receive counter, receive phase detector, and the associated circuitry is in power–
Rx PS/f Rx is set “High”.
If set to 1, both 12–bit and 14–bit reference frequency counters are in power–down mode.
