LPC2148 ADC - kaushikraja1986 - Nov 7 2:01:33 2009

Hii guys.I'm facing a problem with my ADC code on a development board of LPC2148.my reference voltage is internal and it is equal to Vcc=3.45V..I have checked it.The input is at pin 13 i.e., AD0.1.
My clock settings are as follows
pclk -> 60MHz
VPB clock -> 60MHz
ADC clock -> 4MHz
the major problem I'm facing now is that even the output value for a constant analog supply say 3v is not coming steadily.What I'm saying is that I have read the ADC output value from ADODR1 register and projecting it via the LEDs connected to P1.16-P1.23...but each time I'm powering up the board or resetting the board I'm getting different values and that too every value is wrong...I dont know wat is happening
