Hi Customer,
Before you clear PDN to 0, please also clear LPC_AD0CR[START]=000.
This is very important.
Please check this point, and try again.
Have a great day,

Thank you so much Kerry,
That fixed the problem.
I would press the correct answer button if I could find one.
Best regards

I have a similar problem using a LPC-4078. The ADC runs fine until I go into, and then come out of power down mode.
To maximize power saving, I shut off the PDN bit in the CR register prior to turning off the clocks as the users manual suggests. But when I wake up and reverse that process, (turn on clocks in PCONP register and then turn on PDN bit in CR register) I no longer get conversion complete on the ADC.
Any thoughts?
Hi Bill,
The same as LPC1769, please check ADC control register START bit, please set it to no start(0x0) when you clearing PDN to 0.
Please try it on your side.
If you still have question, please contact me!
Please check this point, and try again.
Have a great day,
Kerry
