Look the datasheet of L293D, you will find two ENABLE pins and some selection input pins.

ENABLE pins enable that particular driver section.
Apply different combinations at the other input pins and see the polarity of the voltage at the output (there are only 4 combinations). Note down what should be the input so as to get the required polarity (motor direction). Give those combination from AT82C52.

All the best...

Yes ,it is right, and here is the link of L293D. And you will get the circuit at page 4 of it .
