CMT2310A-EB Evaluation Board Operation Guide
Overview
This Document introduces how to operate the CMT2310A-EB evaluation board (factory default firmware). The
CMT2310A-EB (factory default firmware) and CMT2310A-EM help users quickly evaluate the performance of
the CMT2310A. Meanwhile, CMT2310A-EB can help users to debug, verify and test the CMT2310A functions,
basing on the hardware as a general CM0 level single chip development board.
