When the low frequency clock source, SCLK_LF, is derived directly from HPOSC (BAW), the RTC must be compensated for the HPOSC clock drift over temperature to keep sufficient accuracy to meet BLE Central mode PPM requirements.
In previous releases, the RF driver did this. From this release onwards, the Power driver is responsible for doing so.
In order to enable this feature, the application must call PowerCC26X2_enableHposcRtcCompensation() after Power_init(). For users of SysConfig, this function will be automatically called in Board_init() based on selected Device Config settings (CCFG). All that is required is to regenerate the generated C and H files.
Users that are not using SysConfig or do not wish to regenerate their SysConfig-generated files must call PowerCC26X2_enableHposcRtcCompensation() after Power_init() in their application.
