Answer:
The following figure shows the daisy chain configuration of the ADE911x family of devices with the ADE9178, as well as the functional block diagram of the ADE9113.
Ensure that the connections between X and the Y's are correct, as shown in the first diagram. Pins to note include: /CS, SCLK, MOSI, MISO, and CLKOUT/DREADY.
If all connections are correct, the X will automatically configure the Y devices upon power-up and by writing the initialization command.
You can verify proper power-up and connections by monitoring the voltage and signal levels at the following pins:
In addition, the CLKOUT/DREADY pins of the ADE911x should toggle at the following frequencies:
GNDISO Pin should measure a voltage of 2V.
ALDOOUT Pin should measure a voltage of 1.8V.
REFOUT Pin should measure a voltage of 1.25V.
CLKOUT/DREADY pin of the 1st ADE911x (to which the 16.384MHz crystal is connected) should toggle at 16MHz.
CLKOUT/DREADY pin of the 2nd device should toggle at 4kHz.
CLKOUT/DREADY pin of the 3rd device should toggle at 4kHz.
CLKOUT/DREADY pin of the 4th device should toggle at 4kHz.
Note: If any of these signals are not at the specified levels, there may be an issue with soldering or component damage due to handling.
