| 7 | ADD_ENCODED_PARAMS |
The value of this register is derived from the IC_ADD_ENCODED_PARAMS coreConsultant parameter. Reading 1 in this bit means that the capability of reading these encoded parameters via software has been included. Otherwise, the entire register is 0 regardless of the setting of any other parameters that are encoded in the bits. 0: False 1: True
