Vref output RCM4200

Rabbit

Is the Vref output always available when the processor boots up, or is it only good during an actual A/D conversion. I am not getting any output on my Vref pin, and I want to know if it is a hardware problem with my module, or if it is a software issue.

I have tried to measure the Vref output on the BufIn and the Bufout of the A/D chip on th core board, but there too I only get a few millivolts of output instead of the expected 2.5V

The Vref only has a voltage on it after you initialize the ADC (by using anaIn for the first time, e.g.). I was having the same problem until I realized this.
