7.3.1 RF Initialization Calibration Completion

When rlRfInit is called, the boot time calibrations are run and the application should wait for the RF initialization/calibration completion asynchronous event AWR_AE_RF_INITCALIB_STATUS_SB.

This report indicates the pass/fail status for all enabled boot time calibrations, and whether any calibration data were updated in the hardware as a result of the calibration. The report also contains the timestamp at which calibration was carried out, and the measured temperature at the time of calibration (this is the average of the temperature sensor readings from the temperature sensors located near the TX and RX channels).
