3.8.3 KI_Read_EE_Data<br />
This command reads personalization data (4 data bytes) from the EEPROM of the read/write<br />
device.<br />
Access rights are verified automatically by the read/write device before this command is<br />
executed. If a Read command is not permitted, Status is set to -13 (EEPROM READ<br />
PROTECTED).<br />
C-Function: void KI_Read_EE_Data (BYTE_T num, DWORD_T *data);<br />
