10 / 29 page ver. 2.8 12/01/12 10 ES51980(6000counts) DMM Analog front end with Inrush 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 ES51980. 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 ADC data output for measurement mode: F3/F2/F1/F0 F3 F2 F1 F0 Measurement mode Read data bytes 0 0 0 0 V mode D0(0:18), D1(0:9) 0 0 0 1 ACV + Hz mode D0(0:18), D1(0:9), D3(0:18) 0 0 1 0 A mode D0(0:18), D1(0:9) 0 0 1 1 ACA + Hz mode D0(0:18), D1(0:9), D3(0:18) 0 1 0 0 Resistance mode D0(0:18), D1(0:9) 0 1 0 1 Continuity mode D0(0:18), D1(0:9) 0 1 1 0 Diode mode D0(0:18), D1(0:9) 0 1 1 1 F + duty mode D0(0:18), D2(0:18), D3(0:18) 1 0 0 0 Capacitance Mode D0(0:18) 1 0 0 1 ADP mode D0(0:18), D1(0:9) 1 0 1 0 ADP + Hz mode D0(0:18), D1(0:9), D3(0:18) 1 1 1 1 Insulation mode D0(0:18) |
