We are using an ADE 7878 development board and a 3.3V Arduino to communicate with it using SPI.
We were communicating with it successfully for a period of time but it has now stopped communicating at all.
PM0 is high and PM1 is low putting it into PSM0 mode.
I have noticed that the voltage on the DVDD pin is sitting at 1.5V.
AVDD =2.5V and Vref =1.2 V as expected.
I am not entirely sure what this shows. Is the ADE7878 not powering up properly?
Any guidance what to look at to try and resolve this would be greatly appreciated.
