Continuous TX modes for testing, analysis,  certification

We need to put the KW41Z SoC into different continuous TX modes for testing purposes.


In the SMAC-Connectivity test example there are continuous modes with an unmodulated carrier and different modulated carriers. Looking through the code of that example I found the function ASP_TelecTest ins line 580 of the file MKW41Z_ConnSw_1.0.2\middleware\wireless\ieee_802_15_4_5.3.2\phy\source\MKW41Z\ASP.c. The test mode is set in the function TestMode in line 2596 in the file MKW41Z_ConnSw_1.0.2\middleware\wireless\smac_3.3.2\examples\connectivity_test\Connectivity_TestApp.c


Question 1: A possible test mode that the TestMode function might set is gTestContinuousTxContPN9_c. In the switch statement in ASP_TelecTest there is no case gTestContinuousTxContPN9_c. Which registers do I need to set how in a KW41Z SoC to send a continuous, randomly modulated signal?


Question 2: In the other cases in ASP_TelecTest, the code sets the register XCVR_MISC->DTEST_CTRL. In memory, that would be the address 4005C29C. That register is not documented in the MKW41Z/31Z/21Z Reference Manual. It should be on page 1909, but it's not there. Where can I get documentation about that register?
