10 / 31 page ver. 1.7 12/01/12 10 ES51998(60000counts) DMM Analog front end/Insulation The read command includes one ID byte with ten data bytes. When DATA_NEW is ready1, MPU could send the read data command to get the result of ADC conversion (D0/D1/D2/D3)2 or status flag from ES51998. The next table shows the content of read command.

If MCU access slow ADC output only, ten FADC conversion cycle delay is necessary. DATA_NEW for frequency or capacitance mode will be active when D0 or D3 data ready. 2Note: D0/D1/D2/D3 all are binary code format. D0 is SADC output and D1 is FADC output. The maximum data is 63000 counts for SADC and 604 counts for FADC. The maximum counts for PEAK mode is 103000, so D0 bit 17-18 could be ignored..
