Hi Chris,
Let me try to understand the issue a little better. The DVDD pin is at 1.5V rather than the expected 2.5V and it stays there even after a reset occurs?
During this stop in communication, is the chip simply not sending back any SPI communications, or it returning all high? Anything a little more specific about the stop in communication would be helpful, such as the bit streams in and out. Is the issue still present after doing a full reset and reinitializing SPI communication as the default?
Regards,
