73 / 122 page ![]() Data Sheet ADE9178 REGISTER DETAILS: ADE9178 analog.com Rev. A | 73 of 122 Table 34 shows the registers of the ADE9178 that have bitfields. Additional registers listed in Table 33 table do not have bit fields. Table 34. ADE9178 Register Details Addr Name Bits Bit Name Settings Description Reset Access 0x0AE CONFIG0 [31:30] RESERVED Reserved. 0x0 R 29 CRC_DIS Disable CRC Check. Set this bit to disable CRC check on Host SPI command. 0x0 R/W 28 ICONSEL Phase B Current Calculation Selection. Set this bit to calculate the current flowing through BI from the AI and CI measurements. If this bit is set, BI = −AI − CI. 0x0 R/W [27:25] VCONSEL 3-Wire and 4-Wire Hardware Configuration Selection. 0x0 R/W 000 4-Wire Wye. 001 3-Wire Delta. BV' = AV − CV. 010 4-Wire Wye, Non-Blondel Compliant. BV' = −AV − CV. 011 4-Wire Wye, Non-Blondel Compliant. BV' = −AV. 100 3-Wire Delta. AV' = AV − BV; BV' = AV − CV; CV' = CV − BV. [24:22] ISUM_AUXSEL Neutral Channel Selection Configuration for ISUM. 0x0 R/W 000 Auxiliary 0 Channel Used in ISUM Calculation. 001 Auxiliary 1 Channel Used in ISUM Calculation. 010 Auxiliary 2 Channel Used in ISUM Calculation. 011 Auxiliary 3 Channel Used in ISUM Calculation. 100 Auxiliary 4 Channel Used in ISUM Calculation. 101 Auxiliary 5 Channel Used in ISUM Calculation. [21:20] ISUM_CFG ISUM Calculation Configuration. 0x0 R/W 00 ISUM = AI_PCF + BI_PCF + CI_PCF. For approximated neutral current RMS calculation. 01 ISUM = AI_PCF + BI_PCF + CI_PCF + AUXx_PCF. To determine mismatch between neutral and phase currents. 10 ISUM = AI_PCF + BI_PCF + CI_PCF − AUXx_PCF. To determine mismatch between neutral and phase currents. 19 DIP_SWELL_ONE_IRQ_MODE Dip and Swell One-Cycle Interrupt Mode Selection. 0x0 R/W |
