MCUXpresso Config Tools, an integrated suite of configuration tools, is designed to guide customers from first evaluation to production software development.
The config tools are optimized for designing with Arm® Cortex®-M-based devices from NXP, including general purpose, crossover and wireless-enabled MCUs. 
These configuration tools allow developers to quickly build a custom SDK and leverage pins, clocks and peripherals to generate initialization C code or register values for custom board support
To get the most out of MCUXpresso Config Tools for pins, clocks and peripherals, we recommend pairing this suite with  MCUXpresso IDE and MCUXpresso SDK Builder.
  All runtime software and tools are complimentary. The assembly and C source
  code are provided under permissive open-source licensing. Support is provided
  through the
  MCUXpresso Config Tools Community Forum.
    Note: Supported devices can be found by viewing the
    MCUXpresso Supported Devices Table  
    on the NXP community or by visiting the
    SDK Builder  
    directly and clicking on "Select Development Board." Additional supported
    NXP devices include JN, QN and DSC product families.
