The FAA's summary their words, unchanged
These special conditions are issued to Embraer for the Model CBA-123 airplane. This airplane is equipped with high-technology digital avionics systems which perform critical or essential functions. The applicable regulations do not contain adequate or appropriate safety standards for the protection of these systems from the effects of lightning and high-intensity radiated fields (HIRF). These special conditions contain the additional safety standards which the Administrator considers necessary to ensure that the critical and essential functions that these systems perform are maintained when the airplane is exposed to lightning and HIRF.
