CC2650: What does RFCAdi3VcoLdoVoltageMode( bool bEnable ) do?

Part Number: CC2650

In module rfc.c (Simplelink 2.21.00.06), there's a function called RFCAdi3VcoLdoVoltageMode( bool bEnable ). It is used by the RF driver. What does this function do? The register ADI3_BASE (0x4008 6200) is not documented in the CC26xx User's Guide.

    Stephan,

    the function enables a reference voltage that is used to improve the performance of the synth. I'll make sure the documentation is a lite bit more verbose in the next release.

    Hope this clarifies things.

    Hi Martin,

    We're trying to implement the CMD_RADIO_SETUP, CMD_FS, and CMD_TX_TEST functions outside the RF driver (supplied with SimpleLink 2.21). This, because we need some factory test functions in combination with TI-MAC (which uses SimpleLink 2.11 and does not support the RF driver). All calls report correct statuses (0x400, 0x400, 0x02). However, no signal is being output. So, the digital part of the RF Core appears operational, but it seems that the analog part is not.

    What are the correct steps to do get a Carrier Wave output? (Using TI-MAC 1.5.2 with SimpleLink 2.11)? Could you supply some sample code?

    Do we need to apply override values and/or patches? If so, where can we find the correct values?
