continuous Tx on cc1120 evaluation kit

The "Continuous TX" mode in Studio sets up the radio to send either a unmodulated or modulated signal continuously independent of user input. 

To set up CC1120 in serial mode do the following:

The data pin is updated on the falling edge of the clock pin at the programmed data rate. Preamble and sync word insertion/detection may or may not be active, depending on the sync mode
PREAMBLE_CFG1.num_preamble = Bin(‘0000’) // No preamble, redefine if desired

SYNC_CFG0.sync_mode = Bin(‘000’) // No sync word, redefine if sync detect
                                                                     // and / or insert is desired

SERIAL_STATUS.ioc_sync_pins_en = Bin(‘1’) // Enables GPIO0 for data input during

                                                                                    //TX.

PKT_CFG2.pkt_format = Bin(‘01’) // Enables serial mode.

MDMCFG1.fifo_en = Bin(‘0’) // In/out data through serial pins.

MDMCFG0.transparent_mode_en = Bin(‘0’) // Synchronous serial mode.

Define a GPIO pin (decimal 8) to be serial data clock for both TX and RX operation. For RX operation, another GPIO pin (decimal 9) has to be defined as serial data output. For TX operation, the GPIO0 pin is explicitly used as serial data input. This is automatically done when in TX. In order to avoid internal I/O conflict, GPIO0 should be defined as tri state (decimal 48). In synchronous serial mode the TX data must be set up on the falling edge of the data clock output from CC112X.

Thank you for your quick answer, I going to try it today.
