starts and enables the PRBS9 sequence according to ITU-TO150
Remark: all relevant registers to transmit data must be configured
before entering PRBS9 mode
the data transmission of the defined sequence is started by the
Transmit command
starts and enables the PRBS15 sequence according to ITU-TO150

serial UART lines MX and DTRQ are disabled
enables the output driver on one of the data pins D1 to D7 which
outputs a test signal
Example:
Remark: If the SPI is used, only pins D1 to D4 can be used. If the
serial UART interface is used and the RS232LineEn bit is set to
logic 1 only pins D1 to D4 can be used.
reserved for future use
setting bit 1 to logic 1 enables pin D1 output
setting bit 5 to logic 1 enables pin D5 output
