Low voltages at ADCREFP and ADCREFM pins of TMS320F2810

Hi,

In my 2810 DSP circuit i am using internal reference for my ADC. I have connected 10uf/16V Low esr capacitors so as to connect the ADCREFP and ADCREFM lines to the Ground/ADCLO. But i am getting only 850mV and 550mV at ADCREFP and ADCREFM pins respectively. Even this voltage remains same, if i remove the capacitors and raised these pins from my board. What may be the reason.

Regards
