NEED HELP ON LM35

Hi to all
I am interfacing LM35 with my RCM4010. Before that i have connected two trim pots on two nodes of ADC0808 and got output on PortB with single node using BBoard. But on the another node it seems the node cant be changed using this code:

WrPortI(PDFR, &PDFRShadow, 0x00);
WrPortI(PDDDR, &PDDDRShadow, 0x00000111);

BitWrPortI(PDDCR, &PDDRShadow,0,0);//set A0 high and A1,A2 LOW as selecting node 1
BitWrPortI(PDDCR, &PDDRShadow,0,1);//set A0 high and A1,A2 LOW as selecting node 1
BitWrPortI(PDDCR, &PDDRShadow,0,2);//set A0 high and A1,A2 LOW as selecting node 1
I am using PortD for selecting the nodes. I cant get set this pins high y?
my ADC0808 operates at +5v as ref voltage is +3.3v. However First i need to set this pins high. How can i set this pins as high?

I need a quick reply pls. Its urgent…

Finaly i need to disply my output on webpage. code for this is more helpfull to me…
