06h (pin D6 = s_data) and AnalogTestReg register is set to FFh (TstBusBit) which outputs
the received data stream on pins AUX1 and AUX2.
The pseudo-random binary sequences PRBS9 and PRBS15 are based on ITU-TO150
and are defined with the TestSel2Reg register. Transmission of either data stream is
started by the Transmit command. The preamble/sync byte/start bit/parity bit are
automatically generated depending on the mode selected.
Remark: All relevant registers for transmitting data must be configured in accordance with
ITU-TO150 before selecting PRBS transmission.
