I send the following bytes the ADC to read AVDD: 0x40, 0x06, 0x01, 0x00, 0x76, 0x02, 0xEC, 0xFF, 0xFF
Followed by 0x04, 0x04 to start the conversion.
The expected result is read by sending 3 X 0xFF.
The supply current remains nominal.
I send the following bytes the ADC to read DVDD: 0x40, 0x06, 0x01, 0x00, 0x77, 0x02, 0xF9, 0xFF, 0xFF
Followed by 0x04, 0x04 to start the conversion.
The expected result is read by sending 3 X 0xFF.
The supply current remains 20uA higher!?!?
If I read AVDD again, the supply current drops by 20uA...
