* \brief Internal definitions for the Chirp CH201 GPR Multi-threshold sensor firmware.
*
* This file contains register offsets and other values for use with the CH201 GPR
* Multi-threshold sensor firmware. These values are subject to change without notice.
*
* You should not need to edit this file or call the driver functions directly. Doing so
* will reduce your ability to benefit from future enhancements and releases from Chirp.
