6 Software configurability of Calibrations

mmWaveLink APIs provide API interface to the FECSS (Front End Controller Sub System) RF front end. mmWave link APIs internally call FECSSLib drivers to perform the API functionality and return the status to the application. This section describes the software configurability part of the calibrations by listing the necessary APIs that are used and functionality of each APIs and the recommended API sequences.
