The following
to enable certain digital test data on D1-D6 (see
TestSel1Reg is set to 06h (D6 = sdata) and AnalogTestReg is set to FFh to output the
received data stream to pin AUX1 and AUX2.
Enables the PRBS9 or PRBS15 sequence according to ITU-TO150. To start the
transmission of the defined datastream the command TRANSMIT has to be activated.
The preamble/Sync byte/start bit/parity bit are generated automatically depending on the
selected mode.
Remark: All relevant register to transmit data have to be configured before entering
PRBS mode according ITU-TO150.
