1 = Enable test modes.
1 = Tie the serial bit stream from the digital transmit filter output to the digital receive filter
1 = Tie the analog output of the transmitter to the analog input of the receiver. ANALOG
1 = Tie the digital serial bit stream from the analog receiver output to the analog transmitter
1 = Enable the CLKOUT output; 0 = CLKOUT tri-stated. For test purposes only; do not use
1 = Pulls DC Bias to RXAP/RXAN pins, through 100 kΩ each, to VREF, to be used in testing
0 = No DC Bias to RXAP/RXAN pins.
1 = Control frames occur after one quarter of the time between data frames has elapsed.
0 = Control frames occur half way between data frames.
1 = FS is under hardware control, bit 0 of data frames on SDIN is bit 0 of the transmit word
